Diễn đàn hỗ trợ Firefox

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

Hello. I got a new phone and have lost my Firefox favorites/bookmarks. How do I find and restore them?

After a recent update, firefox has sometimes started shifting my currently-active tab to the end of the list when I click on it. It's messing up my organization, especially when I click on something in a tab group, because when it gets moved to the end, it removes it from the tab group. Any idea how to disable this? I can't find a setting for it.

On some websites, when logging in, my browser will suggest emails and passwords to log in. How do I turn this off? It's really annoying. It does it in private browsing windows as well. I've already deleted all passwords and disabled the password manager in Firefox, but it still happens for some reason.

I use the middle button only for toggling auto-scrolling on and off, or at least that's what I want to do.

That works, unless I mistakenly (often) click the button while over a hyperlinked image or link. In that case, the link opens in a new tab which disrupts my workflow.

How can I set up the mouse in FireFox so that clicking the middle button will ONLY toggle scrolling on and off and never open a link that may happen to be under the cursor?

I've been looking for a solution for this online for ages, and hope there is a setting for this. It's a frustration many times daily.

Whenever I close Firefox and try to reopen it, it brings up a system error that says, "The code execution cannot proceed because C:\WINDOWS\system32\pmls64.dll was not found. Reinstalling the program may fix this problem." I've tried completely deleting Firefox and reinstalling and it opens a new tab, but when I close it i get the same error message.

The Chinese account logs in with empty data and invalid synchronization. If you decide to terminate the cooperation with the Chinese version, you would like to publish a notice and open the synchronization server for the data. So that Chinese users can export their data and migrate it to their international accounts.

I manually pinned some websites on the shortcut row. But when I visit other websites that aren't pinned on shortcuts, they automatically get added to shortcuts.I tried unchecking sponsored shortcuts and also turning off recent activity. But yet when I visit any website that isn't pinned, it automatically gets added to the shortcut.How can I set it up so that only the website I pinned on shortcuts remains and other websites don't automatically get added on shortcut?

sync from my other computer's Firefox doesn't seem to be picked up on the sync for the older computer. any help in transfer of data between the copies of Firefox would be helpful

Good day, I have Firefox 138.0.4 running on Windowx 11 24H2. PC details as follows: CPU = Ryzen 5 2400G RAM = 32GB GPU = RTX 3060Ti 8GB Connection is 50/25Mbps fibre connection

My issue is that when watching F1 from the following site: https://f1tv.formula1.com/, after some time (it differs in how long it takes to manifest), the stream starts to stutter. Note, it is NOT buffering, it is like the stream gets "stuck" or freezes for an instant then continues. The "freeze" then becomes more frequent and sometimes even lasts for about 2 seconds before resuming. The most important fact about all this is that this does NOT happen when using Google Chrome, hence my suspicion that it is somehow related to Firefox specifically. Does anyone have any idea what is causing this and/or how to fix it, please?

Firefox keeps randomly crashing and won't open, sometimes I can get 10 minutes before it returns to crashing all over again. Doesn't even OPEN troubleshoot mode, it just auto crashes.

My drivers are up to date, my windows are up to date, Firefox is up to date, Internet Security software is up to date.

I need this running ASAP for work, each crash report has a different code too which hurts.

First crash happened in the afternoon, yesterday. bp-6580ff2f-d79c-4472-89f6-542c60250604 4/06/2025, 5:15 pm

Firefox will not open on my MacBook Pro. Mac OS 15.5.

Terminal report: 2025-06-04 10:47:20.009 firefox[2076:19473] Server doesn't exist or doesn't provide correct selectors.

Behavior: Clicking Firefox to open results in a window asking for permission to install a new Helper tool. If I grant access I soon see a new window that says the Helper has been installed and I can go to my settings and manage it. Meanwhile the Firefox icon keeps jumping up and down and won't finish opening so I have had to force quit. If I do not grant access to the installation by clicking "cancel" I get the same result: Firefox dances and won't open. I have tried simple solutions like force quitting the dancing icon and restarting after getting the "installed" message. No difference. No difference also if I cancel the installation, force quit and restart.

Please help!

with the new function of Tab Groups i was wondering if it is possible, or can be added in the future, to sync existing Tab Groups to all or specific devices in order to access created groups on my private Macbook to my work Windows Firefox.

thanx for any reply

I have been using Firefox for the last 5 years, I have been content with their services and for that reason I keep using it. Lately I had computer issues so I had to reset my computer and start over this includes Firefox as well. Anyhow because of my lifestyle i do different things like school work, farming, and other stuff. Windows has a feature called "Desktops" this feature is very handy to me as it lets me organize my tabs and windows base on the topic like school or work, (To illustrate this I included a picture of how I have it organize.) well, sometimes my computer shuts down by accident or intentional. Regardless if it was shut down by accident or not, I would boot my computer up and lunch Firefox, and Firefox would open my tabs and windows in the Desktop that It was previously at. For example, I would have all of my school related tabs and windows in the School Desktop, and all of my Work related stuff in the work Desktop, after booting Firefox would automatically place my tabs windows in those compartments, well now Firefox doesn't do that anymore and it is frustrating because every time I boot my computer up after an update or a restart, when Firefox is lunch Firefox will place all of my tabs and windows in the first Desktop, and this is frustrating because every time that happens I have spend time on sorting my tabs out to the right compartment, and to be honest I'm getting sick and tired of doing it because i lose time. So to anyone who reads this, can you please help me figure out what is wrong, because if it is a setting then that's is understandable but if it is Firefox then it would break my heart because as an user and a fan It would break my heart to stop using Firefox as my primary app.
