How to make adobe pdfs load faster in mozilla firefox

Please note: These instructions are no longer up to date

Adobe Reader is the most common tool used to read PDF files, but, by default, it opens up within Firefox and this can sometimes be problematic. PDFs taking a minute to launch is not an uncommon occurence, even on a fast machine. Adobe plugin crashes Firefox on a fairly regular basis as well. Plus, after use, Adobe Reader remains in memory until Firefox is closed. All in all, a pretty poorly-behaved plugin.

The Fix

Since the Adobe Reader can also open PDF files directly, why not just have Firefox download the PDF and then open it in the standalone Adobe Reader program? Well, that’s just what we’re going to do:

  1. Open the Options window by clicking TOOLS and then OPTIONS from the Firefox menu.
  2. Click the downloads icon at the top of the window
  3. Click the View & Edit Actions button in the lower-left
  4. For each of the Adobe Acrobat entries: select it, click Change Action and then select “Open them with the default application” and click OK
  5. Click Close to close the Download Actions window
  6. Click OK to close the Options window

Considerations

The one side-effect to consider is that, now, PDF files must completely download before they are opened, whereas the PDF plugin can “stream” the document and allow you to view the portions that have downloaded. If you have broadband, this usually isn’t an issue. Dialup users may wish to continue using the plugin.

What good is that super fast Internet connection when your browser is running at dial-up speed? This article will point you in the right direction to track down and fix the problem. Of course, if you need extra help with any of this, we have a community of volunteers standing by.

Content you don’t need such as ads or tracking scripts can significantly slow down page loading. Firefox’s built-in content-blocking feature can make the pages load faster by preventing third-party trackers from loading. See Enhanced Tracking Protection in Firefox for desktop for details.

There are also Firefox add-ons that can block content you don’t need, such as:

  • The Disconnect add-on blocks invisible webpage parts that track you online.
  • The uBlock Origin add-on blocks ads, trackers and other unneeded content while using less memory and CPU resources than other adblockers.
  • The NoScript add-on allows you to selectively enable and disable all scripts running on websites.

Sometimes tracking down the source of these kinds of problems is difficult. We have a community of volunteers ready to help you figure it out. See Get community support.

This article will describe how Firefox handles downloads for different types of files and how you can change that behavior.

  • For help with download problems, see What to do if you can’t download or save files.
  • For help with embedded media on web pages, see Fix common audio and video issues.
  • For help changing the e-mail program that Firefox uses, see Change the program used to open email links.

Table of Contents

  • 1 Download actions
  • 2 Changing download actions
  • 3 Adding download actions
  • 4 Resetting download actions for all content types

When you click a link to download a file, you may see a dialog asking whether you want to save the file or open it with a specific application, if Firefox cannot handle the file internally. The Media type, also called the MIME type or Content type, as configured by the web server, will determine what action Firefox will take.

When you tell Firefox to open or save the file and also check the option to “Do this automatically for files like this from now on” (see below), a new Content Type and Action entry for that type of file will appear in the Applications section of the General panel in Firefox Options Preferences Settings .

You can change what action Firefox takes for defined content types. This will not affect media embedded in a web page – only links to the files themselves.

In the Menu bar at the top of the screen, click Firefox and select Preferences . Click the menu button and select Options Preferences . Click the menu button and select Settings .

  • In the General panel, go to the Applications section.
  • Select the entry for the file type you want to change.

    When you click on a link for a type of file that doesn’t have a set content type and download action, Firefox will ask you how to handle the file:

    How to make adobe pdfs load faster in mozilla firefoxHow to make adobe pdfs load faster in mozilla firefox

    • Open with: Saves the file to a temporary folder and opens it in the default application for that file type. To select an application, click Choose. Browse. .
    • Save file: Saves the file to the download folder (specified in the General panel of Firefox OptionsPreferences ).
    • Do this automatically for files like this from now on: Check mark this setting and then click OK to add a new entry to the Content Type list for that file type.

    If you are having problems with how Firefox is handling file downloads that you can’t resolve, or if you just want to start fresh, you can restore the default content types and actions by manually deleting the file that stores these settings.

    Open your profile folder:

    • Click the menu button , click Help and select Troubleshooting Information More Troubleshooting Information . From the Help menu, select Troubleshooting Information More Troubleshooting Information . The Troubleshooting Information tab will open.
    • Under the Application Basics section next to Profile Folder Directory , click Open Folder Show in Finder Open Directory . A window will open that contains your profile folder. Your profile folder will open.

  • Close Firefox. Click the Firefox menu and select Exit . Click the Firefox menu at the top of the screen and select Quit Firefox . Click the Firefox menu and select Quit .
  • Delete (or rename) the handlers.json file.
  • Restart Firefox.

    How to make adobe pdfs load faster in mozilla firefox

    I am trying to file W-2’s on line and one requirement is that my browser must have 128-bit encryption. Is an upgrade available?

    Chosen solution

    All Firefox versions have been supporting AES 256 bit ever since it was Firebird 0.6, May 2003

    If the website you are using claims Firefox does not support even 128-bit then it may be incorrectly looking for the obsolete U that was in Firefox useragents before Firefox 4.0 to show sites it supported 128-bit at minimum. It should not need to since 2002 even.

    So yes Firefox supports 128-bit encryption.

    Hello mholiver, 128-bit encryption is the minimum that you can use with Firefox. :-), firefox already supports 256 since 2002 if i’m not wrong.

    EDIT : Hey, i’m not so fast anymore ? James is faster :-):-):-):-)

    Tired of sitting, tired of reading? Click a button, jump on your bed, and have the article read aloud to you. You can choose from many available male and female voices. You can also set the pitch of the voice and the reading speed. Supports PDF. Supports EPUB (via the excellent EPUBReader extension).

    Read Aloud is a Firefox extension that uses text-to-speech technology to convert webpage text to audio. It works on a variety of websites, including news sites, blogs, fan fiction, publications, textbooks, school and class websites, online universities and course materials.

    Read Aloud is aimed at users who prefer to listen to content instead of reading, people with dyslexia or other learning disabilities, children learning to read, or simply to provide users with alternative way to consume web content.

    Read Aloud allows you to select from a variety of text-to-speech voices, including those provided natively by the browser, as well as by text-to-speech cloud service providers such as Google Wavenet, Amazon Polly, IBM Watson, and Microsoft. Some of the cloud-based voices may require additional in-app purchase to enable.

    Recent developments in machine learning and artificial intelligence has enabled very high-quality speech synthesis. Google Wavenet, Amazon Polly voices, for example, use bleeding edge technology to provide life-like synthetic speech that is close to that of human speech. Read Aloud allows you to use your own Google Cloud Platform and Amazon Web Services account to enable these voices.

    To use Read Aloud, simply navigate to the web page you want to read, then click the Read Aloud icon on the Firefox menu. In addition, the shortcut keys ALT-P, ALT-O, ALT-Comma, and ALT-Period can be used to Play/Pause, Stop, Rewind, and Forward, respectively. You may select the text you want to read before activating the extension. Right clicking on the selected text will provide you with yet another context-menu option to activate Read Aloud.

    To change the voice, reading speed, pitch, or enable text highlighting, go to the Options page either by right clicking on the Read Aloud icon and choose Options, or by clicking the Gear button on the extension popup (you’ll need to stop playback to see the Gear button).

    Privacy Policy

    Personal information
    If you use one of the Premium Voices, you’ll be asked to sign in to your Google account and grant Read Aloud access to your basic user profile, which includes name and email address. We require this information for usage tracking, since the Premium Voices requires making a purchase when usage exceeds the monthly free tier. If you don’t use the Premium Voices, you don’t need to sign in, and no information is collected.

    Browsing history
    We do not track the user’s browsing history. We realize the importance of privacy, so we make sure our extensions require only the minimum set of browser permissions to operate. In particular, during installation, it does not ask for the “Read your browsing history” or the “Read and change all your data on the websites you visit” permissions, both of which could be used to track the user’s browsing history.

    Text converted to speech
    When you select one of the standard text-to-speech voices, the speech synthesis occurs locally on your computer and is never sent to the internet. And neither the input text nor the synthesized speech are saved or stored on your computer.

    When you select one of the premium text-to-speech voices, the input text is sent to our cloud server for synthesis. The server may use your anonymized IP address and User-Agent data for purpose of analytics, abuse management, and service improvement. The server may cache the input text, as well as the synthesized speech, for short amounts of time as part of its normal operation; it does not save them to any type of permanent storage.

    Geolocation
    If you select a voice that is synthesized on our server, your anonymized IP address may be used for geolocation for analytics purposes.

    Issue reporting and contact forms
    If you use the in-app report-issue function or use the contact form on our support website, your comments and information may be kept in our support database for a maximum of 6 months.

    Analytics
    The extensions use Firefox Addons Store’s built-in analytics. Firefox will collect basic extension usage data, including when the extension is installed, invoked, and uninstalled. The extension may also use its own counters to analyze usage patterns. This information is anonymized and do not present privacy concerns.

    To report an issue, please use the “report issue” feature inside the extension. You can also use Support link above.

    Firefox isn’t a slow web browser by any means, but with a little bit of tweaking and fiddling around, you can make it even faster. This is exactly what Fasterfox aims to do. It’s a small extension for Firefox that adds several ways to speed up the browser. It’s designed to boast upload and download speeds, reduce page load times, and can even make video streaming from sites like YouTube faster. The add-on comes packaged with a few presets that let you swiftly switch between different levels of performance. More details after the jump.

    Fasterfox gives you control over various options, but when you open its Options window for the first time, the only tabs available to you are ‘Presets’ and ‘Fasterfox’.

    Presets carry a bunch of different profiles that allow you to quickly switch between different levels of performance improvement, namely ‘Default/Normal’, ‘Courteous/Light’, ‘Optimized/Medium’, and ‘Turbo/Strong’. In case you’re wondering what each level entails, refer to the one-line description under each.

    How to make adobe pdfs load faster in mozilla firefox

    Normal, for instance, keeps Firefox settings at their default, while Turbo Charged raises performance to maximum. If you’re a casual user, using these presets should suffice. Advanced users, on the other hand, might want to tweak performance settings on their own via the ‘Custom’ option at the bottom of the presets tab, which also unlocks the remaining tabs (‘Cache’, ‘Connection’, ‘Pipelining’, ‘Rendering’, and ‘Popups’) in the Options window, each carrying its own set of tweaks.

    Under the Fasterfox tab, you can toggle ‘Enhance Prefetching’ and specify certain keywords for links you don’t want to prefetch when loading pages. Another option within the same tab lets you enable or disable a page load timer.

    How to make adobe pdfs load faster in mozilla firefox

    The Cache tab allows you to specify your desired browser and DNS cache values. Likewise, number of connections made to the server for, lets say, downloading a file, can also be tweaked under its pertaining tab.

    During testing of the add-on, I gave the Turbo Charged profile a shot and the difference it made to the overall page loading speed and video streaming was fairly significant. Most pages seemed to load slightly faster while YouTube videos started to stream without hiccups.
