Firefox Support Forum

After re-installing Firefox, my Bookmarks are gone. I could reinstall them as I go along, but my Folders (used to organize) are also gone. Worse: I cannot seem to figure out how to re-create folders or move those Bookmarks I have. Any suggestions.

I am trying to find answers in relation to my Favourites shorcuts not showing the Icon for some well known websites e.g BBC World News, CNN. Once answer found on the Firefox Forum is: Make sure that you allow pages to choose their own fonts.

Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

This is just typical of many answers I find on the Firefox forums whereby the suggested solutions seem to bear no resemblance to my Firefox system. Am I using something different? Everything points to me having the latest up to date version of Firefox. For example if I click on the four horizontal line hamburger on top right of the screen I do not see anything that begins with "Tools" in the menu options. I see "Settings" and "More Tools" but none lead to "Options>Content: Fonts & Colors> Advanced: [X]. simarly, If I click on "Tools" in the menu at the top of the Browser nothing leads to "Options". Any suggestions please?

Often, when I go to a website with a store, a website called "coupon2deal" (coupontodeal.com) will pop up. It will be at the beginning of my list of tabs, and it will have a miniature tab with no exit button (I need to right-click it to exit). I believe this may have started after I installed the Honey extension, a similar service, but it has not gone away after uninstalling Honey. I tried blocking the site, but the tab still pops up, just with the website blocked.

YouTube keeps blanking out at regular intervals. I can watch videos and try returning to the main page, only to load as blank, with only the menu icon in the upper left corner showing. This keeps happening, and the only solution is to close the browser and use Wise Disk Cleaner (or similar software) to clean the cache before restarting the browser. I have to do this several times pr. Day.

I have tried the most normal solutions I have found, already posted, like:

- Disabling Hardware acceleration - Uninstalling Ad-blockers

I have the following add-ons installed:

- Dashlane - Adblocker Plus - Honey - Return YouTube Dislike - Zotero - Express VPN - LeanLibrary

Are there any other options to attempt to correct this extremely annoying problem? I just want to surf YouTube in peace.

Thanks for any replies in advance!

Just downloaded Firefox a day ago; since a friend told me that its better than Edge. It seemed fine at first and then went and looked at task manager. It's using way more memory than Edge. Firefox has 19 separate tasks running totaling to ~1,500 MB. I need to know what I can do to lower it. My friend made it sound like Firefox was way less memory intensive. I don't even keep 10 tabs open at a time. Any help would be appreciated.

UbuntuStudio 22.04 uses the Firefox Snap package by default. The latest automatic update does not display pages correctly in normal mode, but does work correctly on Safe Mode. Snap.io lists only the latest version of Firefox so I was unable to ask snap to revert to the previous release (prior to 5 Mar 24) and by the time I had tried to investigate the previous version was no longer cached. I did not see a way to force a fresh download of firefox from the latest channel on snap.io.

I tried the snap beta channel for v124, but that exhibited the same problems.

I tried adding a symbolic link to colors.css after seeing firefox complaining that it could not be found when started from the command line. That removed the error/warning message but did not clear the problem with normal mode.

I use the en-GB locale extension only. The technical details about my PC are as follows:

• Operating System: Ubuntu Studio 22.04
• KDE Plasma Version: 5.24.7
• KDE Frameworks Version: 5.92.0
• Qt Version: 5.15.3
• Kernel Version: 6.5.0-25-lowlatency (64-bit)
• Graphics Platform: X11
• Processors: 12 × AMD Ryzen 5 7600 6-Core Processor
• Memory: 30.5 GiB of RAM
• Graphics Processor: RAPHAEL_MENDOCINO

I have now downloaded v123 and installed it in my local home directory, and that version is working well. I have removed the firefox channel via snap. It is likely to be a fault in the construction of the snap for v123 that was not present for v122 prior to 5 Mar 24.

Auto play blocking is no longer working.

media.autoplay.block-event.enabled true media.autoplay.blocking_policy 3 [tried 2] media.autoplay.default 5 [tried values]

Anyone have good values that block auto playing videos?

I want certain extensions to be able to run in private windows, but not in normal windows. For example, I would browse normally without a VPN extension, and when I open a private window, the VPN extension would be enabled.

Firefox automatically updated to 123.0. Now the only tabs that will open are to support.mozilla.org or similar mozilla.org links. Everything was fine this morning, but now nothing works. This is problematic because I have a lot of tabs open for different sites that I work on daily.

I open a website (opentable.com) and it opens momentarily then the screen goes blank white. I can open the site using microsoft edge.

Something has changed as this previously was not a problem

hi, when I am using Firefox to play a media file - both audio and video - an icon is placed in the menu bar - which can be used to navigate the media file. (i.e. stop/play/pause, ff/rw etc.)

is it possible to tweak Firefox so this icon does not appear?

I cannot find a parameter in Settings to turn this feature off.

cheers, Stephen

As of a few days ago my login to my bank's website is not working. I can login, but the main page which should display accounts, etc. only displays the top half of the site, but not the lower half that should display the account information. I tried chrome, and that works fine. But I was wondering why FireFox is not displaying the website. I've been in contact with my bank and their I.T. department. And they claim there have been no changes or glitches, and their website should work with all majore browsers, including F.F. I do have a password manager, but I disabled that for the bank website. I've cleared cache numerous times. Rebooted, etc. I know there was a Microsoft Windows update a few days ago. In fact they sent 2 updates almost back to back. Which is unusual. I understand there have been cyber attacks recently. Don't know if that's related. Any ideas on how to get F.F. working on my bank's website? Thanks

I am a startup founder. I'm making a webgl rendering engine. I'm doing a stress test with 4 large paragraphs amounting to tens of millions of triangles on a macbook air. Firefox is on the latest version.

When I run the app in chrome/safari/opera, the performance is normal. ~45fps. But in Firefox, it's very slow. My FPS counter (in a requestAnimationFrame loop) says ~45fps on all browsers. But in Firefox, even though the counter says that, the real frame rate is ~3-5fps.

When I try to profile, the problem magically goes away and we're back to ~45fps. I played around with profiler settings, and the key determinant is whether or not I'm taking screenshots. No screenshots = slow. Screenshots = fast.

In the flame graph, in slow mode (no screenshots), it seems like I get stuck in the canvasRenderer and the Renderer mostly waits for it. But in fast mode (with screenshots), the canvasRenderer keeps up and the Renderer spents most it's time in: iokit_user_client_trap

I'm not sure what to do. This is only a problem on Firefox. There's some sort of gpu/threads/something that switches when I profile with screenshots that makes it way faster. This performance hit basically ruins my app for Firefox only. Any idea what I should do?

In a sub folder, no messages show, but, above where they should be (above the column titles), it tells me there are 2 messages. How do I get to see them and stop this ever happening again?

Firefox uses 2.1gb of RAM with 6 tabs opened which is far more than it ussualy does and it sometimes just jumps to 2.5gb. ((Fore the Image) My task manager is in german so Arbeitsspeicher=RAM)

There is this new pop up coming on latest firefox version 123 about opening favorite link on firefox, I want to get rid of it programmatically using java, which argument or preference should I use ?
