I installed Firefox years ago. This morning, when I click on the browser icon, I get this message: Error platform '127.0.2' is not compatible with minVersion>= 127.0.1 maxVersion<= 127.0.1

What is going on? The browser updates itself so I don't do anything. But now, it doesn't work. I use an alternate browser to send this message to you.

Hello,

Recently, my Firefox has stopped opening and immediately closes upon start-up. The window asking if I would like to start in troubleshoot mode briefly flickers on the screen a few seconds later, and I am unable to start it in troubleshoot mode. I also have this problem with Google Chrome, but not with Microsoft Edge, which still works fine. I also downloaded Opera and I found that Opera works fine as well. I have tried various solutions I found online and none of them have worked yet. However, when I started Windows 11 in Safe Mode, Firefox still wouldn’t open initially but this time it did let me open troubleshoot mode, which I was able to succesfully start. In troubleshoot mode, I turned off hardware acceleration and all my extensions, and once I exited troubleshoot mode, Firefox was able to start normally in Safe Mode. However, I do not know if hardware acceleration or the extensions actually caused the issue because even if I turned them back on, Firefox continued to run normally in Safe Mode. Once I exited Windows Safe Mode, however, Firefox still continued not to open, and I still couldn’t access troubleshoot mode. Using the shift key trick to open Firefox in troubleshoot mode doesn’t work either. I would appreciate any help I can get with this issue.

I've just tried to save something from firefox on linux(Manjaro KDE) and was baffled that there doesn't seem to be a way to manually enter the path and navigate to it in the save dialog. In addition to that, there are many locations missing and I can't seem to find a way to add new custom or favorites ones either.

All that combined means it was impossible to save my file directly to a network location, which is something I very often need to do. It just seems insane for such a basic feature to be missing and I've found a 4 years old thread about it meaning nothing has been done to fix this since? https://support.mozilla.org/en-US/questions/1279125

The only way I can see would be to mount the network path(not a good solution for one offs) and navigate to it(a symlink can make it closer to one of the existing shortcut but still annoyingly require more clicks) every time but that's very tedious since most of my saving is on a specific server drive.

Firefox 115.12esr slow to startup takes up to 10 second to load the first time now Firefox was fine in version 112.esr. to bad Firefox forces updates, even when the update make Firefox worse. https://snipboard.io/QF0ERT.jpg of course it works faster without extensions, that does not mean anything. I would reinstall the older version but Mozilla fixed so we cannot. I do not have time to reinstall all the extension so I am left with a useless Firefox. To bad Firefox does not allow reinstall of extension automatically, a reset of Firefox would also make Firefox useless; I am at a loss to how to continue to support Mozilla and not switch to another browser?

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas

About 1 week ago Firefox with Windows 11 stopped displaying YouTube video comments. I've tried other browsers and I can see the comments.

I only have 6 extensions and have disabled all of them and still have the problem. With Firefox in safe mode the problem goes away and I can see the comments. I've cleared the Firefox cache and hardware acceleration is off. I have the standard themes and using the default system theme-auto.

Any suggestions on how to resolve this problem? Thank you.

I am using Windows 11 and FF 127.02. I have read the lag issue with Youtube was suppose to be corrected with FF 127.02 but it is not. I have been using FF for many years now an love it. It is my understanding that it is the ad blockers causing the slow down. Do you have an estimated date when this will be resolved. I have tried every trick included running it in diagnostic mode or trouble shooting mode. Nothing seems to work. Not even a refresh.

Thanks

When I click on a Firefox menu (File, Edit, View, etc.) or the hamburger menu, or a drop-down menu on a web page, the menu appears. Then, when I move the mouse to hover over the menu, the menu vanishes. If, instead, I hold down the mouse button, I can move over the menu without it disappearing.

I'm using a focus-follows-mouse window manager (VTWM) and I think, somehow, Firefox is getting a focus change message when the mouse moves onto the menu. I think this because of the way the Firefox titlebar flickers from showing it's the active window to the inactive window, then active again, once the menu disappears.

Please advise.

Thanks, Richard

Please excuse me if I miss any details.... this is my third time trying to submit this issue.

I will just skip to the meat of it this time. I'm getting this error while working from my localhost. I have been working on a personal project for years with this set up with no issues until today. I can no longer click on the errors in the console log and be directed to the Debugger tab. When I click on errors, nothing happens. If I try to open them in a New Tab, I get the error below:

The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (webpack) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address.

I have also noticed firefox does not even load all the files until I refresh it at least twice. Even when it is all loaded properly, the error persists.

I have tried: - restarting firefox - restarting my computer - clearing ALL cache and cookies - running firefox in safe mode - disabling all add ons - disabling performance mode (was already off) - checking network.protocol-handler.external.javascript = false (it is)

Let me know if there is any other information I can provide. I really dislike having to work in chrome for this so I hope I can find a solution as soon as possible.

After upgrading to fedora 40, firefox just takes ages to boot up, even when it's running if I want to open a new window it still takes ages to run. I have tried uninstalling it and deleting it's data but with no luck. The issue still presists.

There is a problem logging into Disqus. (disqus.com and disquscdn.com)

This is affecting Linux and Windows installations.

Page I'm having problems at www.lawyersgunsmoneyblog.com

I have used the troubleshooting mode and caches have been cleared and all extension disabled with no luck.

Other browsers are functional. The log in doesn't appear at all:

Trying to stream shows on Firefox and video does not start / errors out. Philo returns with this error: Philo is having trouble streaming this content.

[Error code: pf-1.5-5bb2f]

Paramount+ Also freezes up and returns error message. As does Amazon Prime.

Adblockers disabled. Youtube is fine.

Tried refreshing Firefox / renistalling but same error. Prefer to use Firefox as default browser but having to go to Google to stream shows.

Debating rolling back a version but it was working fine the other day but could have had an update and didn't notice and now streaming is erroring out.

Suggestions? Thanks.

I have been using Firefox for many years and I have never had problems, until now, out of nowhere Firefox closes and the little window opens that the report is being sent to Firefox, but I can no longer restart or open Firefox, until I reset the computer, This can happen one, two, three and even four times a day, making it very uncomfortable to reset the computer.

I have already tried many ways to solve the problem, from completely uninstalling Firefox and reinstalling it, I use very few extensions, I already disabled WebGL and also disabled hardware acceleration, nothing has worked, when Firefox closes, I cannot open Firefox Developer either and That browser was not even open at the time of the failure with Firefox.

Hello,

Whenever I open a local HTML file, Firefox tab will crash. This happens if the HTML file size is big (>4MB), smaller file doesn't crash.

I've tried opening the file on Chrome, it doesn't crash and open just fine. So it seems like this is a bug with Firefox.

I've uploaded the HTML file if anyone wants to test: https://www.mediafire.com/file/ipmu7ugrd2vvelr/LICENSES.chromium.html.zip/file

Thanks

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

I get this error in my console XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: libwayland-client.so.0: failed to map segment from shared object Couldn't load XPCOM.

I am using the latest version of firefox. Windows 10. I'm writing a school project with assistance from ChatGPT. When I ask it for a link, it provides it. While it is "typing", I can see the link, but when it finishes "typing", the link becomes a blue word "Link", with the web address gone. I can not click on it to open the website, like I can in Mirosoft office. There is no way to access the website. I tried to use troubleshooting mode with all extensions disabled - it didn't help. ChatGPT claims, that it's the browser issue. How can I access these links?

Firefox hangs for 5 seconds between every type of download between the "Ok" of the "Save As.." dialog and the actual download of the file.

Any ideas how to resolve the issue or troubleshooting tips?

I'm currently using Firefox 108.0.2 (64-bit) on Windows 10 Pro 22H2

Thanks!

I tried to Connect Dropbox to my desktop, but the page would not load.

Chrome has no problem loading the page.

Could someone please let me know if they have the same problem

I am using Firefox in a Linux environment with multiple workstations, where I may be logged into more than one workstation at once. The workstations have an auto-mounted home file system such that my home directory (including my Firefox profile directory) are shared.

Because of this, when I try to launch Firefox on a second workstation, I get an error saying "Firefox is already running but is not responding". I have read the support articles about this issue, and other community support threads, but none of them address this use case.

I wish to use the same profile, so that I still have all my bookmarks and such, and have them continue to stay up-to-date. How can I do so in this environment?
