5 Firefox extensions to manage Flash usage

Flash on Linux sucks. Maybe now a little less than before, but it is still a rather unpleasant experience (it consumes too many resources and does not have the same performance as that experienced in Windows).

Fortunately, HTML5 is replacing it in many respects, but it seems we still have Flash for a while. For that reason, we recommend some extensions for Firefox to help you control Flash usage.

1. NoFlash

NoFlash is a Firefox add-on that replaces the YouTube and Vimeo Flash player on third-party pages with the HTML5 counterpart.

2. Flashblock

Flashblock is an extension (plugin) for Google Chrome and Mozilla Firefox, which allows us to block all types of Flash content.

Through Flashblock we can block Flash content, even do it with entire pages, or activate only those that we want to see or allow all content, depending on our taste. It also allows us to define a white list or allowed list where we can specify sites where we can see Flash. A clear example for this would be YouTube, although although much of the page is already working on HTML5, there are a significant number of videos that still work under this Adobe technology. So through Flashblock we can define that this page "always" show us Flash content, without having to specify it every time we enter the site.

3. Video DownloadHelper & Flash video downloader

Their names say it all: do you want to download videos from MySpace, Google Video, DailyMotion, pörkölt, iFilm, DreamHost, Youtube and so many others? Do you want to automatically convert them to your preferred video formats? Be sure to try these 2 excellent extensions.

4. FlashResizer

If you are browsing the web and want to change the size of any flash element then FlashResizer, an extension for Firefox, can be very useful.

By means of a green vertical line that is added to the objects in flash, you will be able to make the changes as well as return to the previous size by just double clicking on that line.

It is ideal to apply in flash games, YouTube videos and other similar sites where we want to resize the player for a better experience.

5. FlashFireBug

FlashFirebug is a Firefox extension that allows developers to debug Flash AS3 files on the web, in the same way as if they were debugging an HTML file.

The main purpose of FlashFirebug is to make debugging a flash file as easy as debugging an HTML or Javascript, as it has an interface derived from Firebug, which makes it familiar to developers.

To use FlashFirebug, you must have Firebug installed and Flash Player content debugger 10 or higher (compatible with Netscape browsers).

    As we say here in Chile, Flash is worth shit.

    I have been using FlashVideoReplacer for some time and although at first the experience is somewhat late, it is something to get used to. Your machine will thank you.

    Good contribution! Thank you!

    Don't ask why, but on my Debian 60, using flash-nonfree, everything works much better than on a W7 Ultimate x64 SP1 booted on the same machine.

    Debian 6, sorry. My cat screwed up 😛

    To the ball ... everything can be. : S
    Anyway, it should be noted that flash performance improved a lot in the latest versions for Linux ... although, of course, it still lacks.
    A hug! Paul.

    Yes. Although in Ubuntu 10.10 (same machine of course), it is still creepy (flash-nonfree) ...
    I was also surprised by the Debian thing.

    We also have LightSpark (Well as I only watch YouTube videos with Firefox 5) it consumes me much less 10 MB of memory, while the FlashPlayer consumes me at least 70 MB and maximum about 384 MB of memory
