Firefox Support Forum

I'm running an up-to-date rev 68.0.1 (64-bit) version of Firefox on Windows 10. When I click on the avatar in the upper right portion of the Firefox toolbar, I see that I'm signed in to my Firefox account as me. So... how do I sign out of my Firefox account? Can't find a control anywhere.

Hi,

The version of Firefox 68.9 on Linux CentOS 8.2 has problem playing videos from https://www.udemy.com Testing on macOS and Windows 10 the Udemy Courses are presented fine. I get dark video.

I'm using Firefox 68.0.1 on macOS Mojave 10.14.5. When I go full screen, the tabs and address bar remain at the top of the screen. I can't make them go away. I've tried:

- Installing plugins (I tried a couple) - Disabling Add-ons (Safe mode) - Resetting Firefox - Disabling hardware acceleration (and restart browser) - Using different techniques to go full screen (Cmd+Shift+F, Cmd+Ctrl+F, Zoom menu) - Scrolling or clicking in the canvas to ensure focus

No matter what, the tab bar and address bar remain on the screen (see attached screenshot). I've also attached my browser config (filtered on "full"). Is there any way to get a full-screen experience in Firefox?

I use firefox and just got a new pc. I want to have the same bookmarks toolbar on firefox on the new pc. How do I export my bookmarks toolbar from my old pc?

I tried exporting/importing the "bookmarks.html" file, but the toolbar on the new pc is empty. The bookmarks toolbar was not exported.

Do I have to recreate the toolbar by hand, one site at a time? That's very bad. I have literally hundreds of bookmarks on my firefox toolbar.

I can't view WebGL content anymore. It used to work until a few weeks ago (sorry I can't be more specific). It works OK on other browsers on my computer.

How do I get WebGL working again?

Today, I was designing a new webpage. It uses fonts like Open Sans etc (directly embedded via css, not via Google Fonts). After the update to 68.0 (from 67.0.4) the fonts aren't shown any more and Arial is used for everything. It only happens when opened the html-files locally. If you upload the same files to a webserver, everything works fine. With 67.0.4 (and all previous versions) the website works fine both ways. OS is Windows 10, 64 bit, Professional.

I was running just "regular" Firefox on my Windows laptop. Yesterday my help desk had me upgrade to Firefox Extended Support Release to install a corporate email security certificate. I did not know when I installed this version of Firefox that it would overwrite my existing browser, and when it did, I lost all of my add-ins, extensions, bookmarks, etc. I'm hoping to be able to restore my old profile with all of the existing data I had. If I have to "downgrade" to regular Firefox I think that's fine since I just needed the ESR to install the security cert and that's complete now.

I looked on the about:profiles page and I have two other profiles, default and june19 (I presume the latter is from June 2019?), but I don't know how to determine which one is the preferred one. When I clicked Launch profile in new browser, it instructed me to create a new profile to protect my information and I hesitated to do that because I'm trying to restore an old profile, not create a new one. In case you can't tell, I'm not an advanced software user, so give instructions like you would to a 5-year-old or your grandma... lol. Thanks in advance!

After Firefox updated to 68.0 the other day, I have found myself being plagued by it making multiple processes in the Task Manager yet again. I have already tried the following:

1) Already tried about:config to change browser.tabs.remote.autostart.2/browser.tabs.remote.autostart from true to false. It is set, but absolutely nothing has changed.

2) I have tried going into Options>Performance and limiting the Content Process Limit to 1 instead of 4. The setting was saved, and yet it has not changed a thing.

3) Ending these processes only results in my tabs crashing, and reloading them only adds another Firefox process.

But as it turns out here: https://www.ghacks.net/2019/05/17/going-forward-multi-process-cant-be-turned-off-anymore-in-firefox/ Firefox has removed the option to turn this off entirely after updating.

My computer can't handle having more than 1 Firefox process open and I want to disable multiple processes, otherwise everything will lag horribly. Is there any way I can permanently disable the multiple processes?

long story short l had to reinstall my laptop, it was long overdue (by two years lol) now lve gotten everything reinstalled but lm having a problem getting my tabs below my bookmarks toolbar, the userchorme.css l kept a backup of doesnt seem to be working any more, surely theres a simpler way to sort this now, or if someone could direct me to some working code to get me tabs back to below my bookmarks toolbar ld be extremely grateful..

I liked the idea of pinned tabs because I was thinking of them as being a way of having multiple "homepages", i.e. when I open my browser, they open automatically. However, they're stored in session data, which means that pinned tabs get lost whenever I close my browser because I have Firefox set up to clear a bunch of different session/history data on close. I'm not sure which setting is causing this, but I'd like a way to have a page open on startup without having to compromise my privacy, so I'd prefer to just pin tabs on startup somehow without having it be related to session history. Is there any way to do this?

I'm having a lot of trouble with the URL autocomplete function not working. I have been trying to solve this for a couple days and nothing is working to enable the URL autocomplete. Here are some of the things I have tried - does anyone have any ideas?

Thanks so much!

-Made sure the browser.urlbar.autoFill item is set to 'true' -Adjusted Firefox History settings to 'Remember History' -Adjusted Firefox Address Bar settings (Browsing History, Bookmarks, and Open Tabs are checked) -Cleared cache and cookies -Reset Firefox several times -Reinstalled Firefox (without deleting profile and Firefox data)

I have attached screenshots of how my 'about:config' looks, as well as the 'Important Modified Preferences,' in case there's an error that someone else can catch.

(I am running Firefox 68.0.2 on macOS Mojave Version 10.14.5)

VR kit used: Valve Index

Hello,

WebVR implementation in Firefox has improved significantly but still some bugs are prohibitive from using it reliably. More specifically, integration with SteamVR appears to be problematic. Here's a test scenario.

How to replicate the problem:

0) Ensure SteamVR is installed and operational, using a compatible VR kit.

1) Visit https://sketchfab.com/AliceVision/models

2) Open one of the models and select the VR icon (bottom right).

3) Once the 3D model is presented in the VR headset, close the 3D model from within the web page and return to the list of 3D models (main page).

4) 1st issue: Notice that in the headset, SteamVR shows that it's waiting for the application (Firefox in this case) to respond. This should not normally happen, i.e. when Firefox has no content to present, it should present a default 3D scene, for example: a dome with a firefox logo in the middle. Also, if you click on the System Button on the VR controller, the SteamVR Dashboard pops up BUT it does not offer the option to disengage/disconnect Firefox from SteamVR. That keeps SteamVR locked into Firefox. If you wait long enough, you get the ERRORS shown in the attached images.

5) Open another 3D model and click on the VR button. The new model should appear in the VR headset.

6) 2st issue: The VR controller is not longer tracked by Firefox.

I hope you find the above useful and easy to replicate. If you need additional information, please do let me know.

Kind regards

When maximized, a block box in the top-left corner of the browser covers the favicon of the first tab. When not maximized, the tabs shift to the right such that the box is no longer covering any part of the first tab.

When I start with add-ons disabled, the black box disappears. However, setting my theme to default, removing all my add-ons, refreshing and then re-installing Firefox didn't fix the problem.

I also noticed that if I enable the menu bar, the black box leaves the tabs alone and instead covers the 'File' menu.

Any idea how to get rid of it?

If I select 'simplify the page' in print preview most of the time all pages display and print. Otherwise, it only displays a third of the webpages when printing (ANYTHING to ANY PRINTER including PDF).

Hello,

Both Firefox dev and standard are having a problem where if i leave my browser open for some time the CPU usage goes up and it will use all 32GB of my memory until it crashes my PC, this is a content thing.

I have tried clean uninstalling both and it has fixed nothing it has gotten so bad that i need to restart firefox every 30 minutes or so I might need to swap over to an other browser at this point.

thanks for any help i can get,

While using FF 68 and setting network.trr.mode to a value of 3 no resolution of any site works. This mode only uses DNS over https and does not fall back.

Is DNS over HTTPS DOH work in this mode?

1. Fresh FF install on freshly installed Xubuntu 19.04 in Vbox. 2. FF started ok. Open different tabs, certain sites at different stages crashes with 'Gah. Your tab just crashed' message: (just a few examples of sites below)

2a. Technet: https://social.technet.microsoft.com/Forums/windows/en-US/cf6ceadd-4bb4-4668-b8fb-8ccf7d067e31/diagnostic-policy-service-high-cpu

2b. http://www.ctrip.com/ - Started to load, but when it is almost fully completed, it crashed.

2c. mail.yahoo.com - After keying in user name, the next page for password crashes.

3. Steps tried: Had googled left right center but nothing of help. Some articles that seem close, tried but failed: 3a. disable multi-process tabs doesn't help :

          browser.tabs.remote.autostart = false 
          browser.tabs.remote.autostart.2 = false  (can't find this part though, only the above line)

3b. Disable hardware acceleration - doesn't help.

3c. There is no extension nor theme added, it's a newly installed FF and OS.

4. What works: safe mode. All the sites listed above are able to load in safe mode.

5. There is no crash report? Is it because it is a tab crash rather than a full crash?

Please help ...
