Hi a lot of websites I visit are not displaying the font correctly when using firefox. I have set "Allow Web Sites To Choose Their Own" already in the preferences. See image below for example. It's happening a lot at the moment . I have updated to latest Firefox and Mac OS is latest. Pages are fine when viewed in Chrome. Help please! Cheers- Vince

Currently on Firefox Developer Edition 89.0b2, clicking menu > Help > Submit Feedback, takes me here: https://mozilla.github.io/imo-placeholder/

It's a blank "Coming Soon" page with no information.

I'm experiencing usability problems with the new theme and I'd like to share what I'm experiencing.

Hello everyone! The mail client crashes with an error while sending a message. In this case, the message is sent. Installed a new, clean Windows 10. And a new mail client.

I have Firefox installed on an XUbuntu 20.04.2 LTS machine. preferences to "restore previous session" on startup. Intermittently, when I launch the browser, one of my windows has a very strange appearance (please note the general look of the window in the attached screenshot and ignore the "page cannot be displayed" message, as the screenshot was taken when I was not connected to the Internet.)

I have already tried reseting Firefox and that does not make the problem go away permanently; it always comes back eventually. (Note: I cleared cache before, and cookies after, taking the screenshot but before opening this support request. So the "troubleshooting information" attached reflects how it is after cookies are cleared.)

I have just updated Mozilla VPN. Now when I attempt to load Mozilla VPN I receive the message "Loadlibrary failed with error 87: The parameter is incorrect." and nothing happens. I have Windows 10, have run Windows Update a few times, uploaded and installed all updates found and the error still occurs.

I hate that this June Firefox update has double or triple spaced my Bookmarks drop-down menu. I had just the right amount of folders and links that could expand to the bottom of the screen and now it goes well off the bottom of the screen and requires scrolling back up and down to use the links I use for the office on the 24" screen. Worse, my Firefox syncs with my laptop at home so on that 15" screen its even an even worse problem. I can't find a way to close them all up the way they used to be. There was nothing wrong with the browser as it was. If anyone wanted a new look, they could select different themes rather than force this arbitrary update on all of us.

Please please restore version 88 - this 89 version actually is painful to me visually - very harsh. I am not a techie - do not understand answers that try to change code. Just get rid of this horrible change - it's so bad I'm thinking of getting rid of Firefox

I have very recently upgraded to Version 89.0 (Windows 10) and I can't help but wonder why some key characteristics have been changed for the worse. The display format for the Bookmarks list is now spaced so large that my Bookmarks no longer fit on a single screen, and I can find no adjustment available to users. Also, the new tab screen no longer shows the image of the page, making the display less useful. What was broken in these features that Mozilla found a need to "fix" them? Is there anything a user can do to "undo" these changes?

I will have only 5 tabs open and it will go up to around 1000-1100 MB. I have tried refreshing Firefox a bunch, uninstall and reinstall extensions, clearing the memory in about:memory, and have tried getting help on reddit as well. I love the look and snappiness of Firefox, and want to use it badly, but can't due to this fact. Can someone help me?

First of all, I somewhat recently switched from Chrome to Firefox on my Android mobile. And that was solely due to Chrome's continuous bad updates which ruined the UI.

Well an issue arose today whilst I was attempting to access my work email, I couldn't type in my username or password. In fact it appeared I couldn't type anywhere, on the Google home page, nowhere. YouTube, Chrome, and rest worked just fine, only Firefox had this issue. So that ruled out something being wrong with the phone itself.

Restarting my phone 'fixed' the issue, though I wouldn't like to use the word fixed as I have no idea why it occurred in the first place, therefore I must assume that it can very possibly occur again. I'd rather have it not.

My password extension doesn't work in private window mode. When I look at the extension in Firefox, the mask shows next to it, indicating it should work in private mode. Is there a setting I'm missing?

I have two laptops and a mobile phone that are connected to Firefox and have sync operating. One the laptops shows a location of Wrexham which is approximately correct. The other shows a location of Boardman, OR, United States, a place some 6000 miles away and of which I have never heard. Googling the location gives me no useful information, other than it is a small town with no special characteristics. A screenshot of part of the Firefox Accounts page illustrates what the situation is.

The laptop stated as in Boardman has a location set within Windows. That is not Wrexhan but is only a few miles from there.

I have used iplocation.net which gives me the location of my ISP, in England.

I sometimes use a VPN (for work) and when being used iplocation.net gives a different English location which I think is the locaton of the ISP for my Employer.

I am unsure what is going on here nor do I know what implications there are for my security. I do not seem to be able to fix this.

Can anyone help, please?

NY Times now won't load images (there's now a hold-to-see button; image & headlines vanish when you let go) on either side of the firewall & YouTube blacks out their link icons & the right column recommended / loaded-for-sequence play videos on the right column whether you're signed-in or not. Background images are now blacked out on some sites. None of this ever happened to me until I upgraded to FF 89.

Why is this? How do I stop it?

The array of Mac settings, FF settings, site settings is dizzying as we all know, which makes sorting out where the problem might lie a bear w/o help. Things worked great through 88. I allowed FF entree to simply install each new version. No prob. Now this. 89 is clearly a complete overhaul -- I've seen scores of comments from folks left aghast at these changes with no clear, comprehensive tutorial of 1) what exactly FF did & changed, 2) why FF did it & most importantly, 3) how to return which sections / settings to what you wanted & felt comfy with & which you're just stuck getting used to. Configuration ability is a huge aspect of computer living. That FF info alone would have lessened the heat I'm afraid you've been taking.

Anyway, back to mine... any clue as to how to reset whatever it is that needs resetting to drop this blockage? Many thanks for the assist!

1. This started happening since the last proton update.
2. When I open Firefox, it's completely white.
3. I can guess and press the minimize, maximize, and close keys but nothing is visible.
4. I tried opening Firefox in safe mode from command prompt, but even the UI for the prompt for it is white.
5. I am not sure what to do from here on out.
6. Please help. I am unable to use the browser since the proton update.

Following a recent update to version 89, a previously stable Firefox installation is now almost completely unusable. Just getting to the point of getting to this page where I am writing this post has seen THREE Firefox crashes, as switching tab to my email so as to get the verification code for my mozilla account was seemingly too much for Firefox to handle. Viewing Facebook messages and scrolling up to see comments made earlier in the day sees the layout of the page completely screwed up (main content shifted to bottom right corner, scrollbar shifted elsewhere, part of the page blank) and at that point trying to switch to another tab creates a strange hybrid situation where some of the contents from both tabs is merged together and is then the only content visible no matter which tab is then clicked on. Using Google Maps works for about 30 seconds and then the entire page flashes repeatedly with every move of the mouse, before this triggers a browser crash. I can be reading content on a news website and suddenly the tab crashes for no reason, and in most cases the browser then crashes thereafter. Restarting the browser and the news page tab will be shown and begin to load but then immediately crashes. These are just some of the issues that have occurred within just the past 2 hours, but this is a cumulative effect as Firefox has been becoming increasingly unstable to this point after updating to version 89 earlier in the week.... No other changes have been made since updating Firefox, here has been no Windows 10 updates, no other applications have been installed or updated, no other software has been either added or removed.

I could run the previous version of Firefox for several days, leaving the computer running but idle for a few hours each day, and still come back and resume where I had left off without issue. Now with Firefox 89 it is struggling to even go 30 minutes without tabs or the entire browser crashing. When can we expct a fix, or is there otherwise a way to roll back Firefox to version 88 without having to do a full uninstall/reinstall...?
