Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

Hi,

I have tried to sync between my two computers, but it did not work out well:

e.g when I click on ‘show more bookmarks (>>)’ on the right side of the screen (next to Other Bookmarks) I get - Firefox is not responding and I have to click on

-> Close the program.

If I click on -> Wait for the program to respond - Firefox never responds! And before I click on -> Close the Program - my keyboard input is totally erratic!

This occurs on both computers! - what can I do…..

I have therefor on the computer I want to be on the receiving end:

- deleted: History, Downloads and Tags and All Bookmarks - Cleared browsing data and cookies - Closed all open tabs

And now I am Signed in with Syncing; ON - on both computers again.

But I have not checked any of the check-boxes in ‘Manage sync…’ - ‘Manage what syncs on all your connected devices’ i.e. Bookmarks, Passwords, settings, History, Payment methods, Open tabs, Add-ons

Why is there no check-box tag groups!

What do I have to do on my SOURCE compute and on the DESTINATION computer for - a one way sync of everything?

Best regards, Einar

PS,

After Signing in I was presented with the following, and I chose Not Now

Sync your Firefox experience View your saved passwords, tabs, browsing history and more — across all your devices. Select an option to continue:

- I already have Firefox for mobile Start your sync now if you already have Firefox on your mobile device. 

- I don’t have Firefox for mobile Download Firefox on your mobile device, then start your sync.

Not now

I recently needed to reinstall Firefox to attempt to deal with an issue. It turned out Firefox was not the cause but when the new browser opened, it did not have the Home icon on the toolbar.

I went to "Customize toolbar" and added it but now it shows up on the far right end of the toolbar. It used to be to the left of the URL area. I tried to grab it with the mouse and drag it but it won't move.

Every time I need to jump to a home page I end up going where it used to be. I realize this is small potatoes but is there any way to get it back where it used to be?

Forum users : Gmail on my Windows 10 PC runs very slowly when the Lastpass extension is enabled. This ONLY happens with Gmail. In fact I get an alert that Lastpass is slowing down Firefox. Gmail is fine when the extension is removed. Has anyone else encountered this problem? If so have you found a solution other than removing the Lastpass extension?

Thanks!

I'm using the vertical tabs feature. I also tried enabling the "Expand sidebar on hover" option, which minimizes the side bar, and only expands it when you hover on it.

Issue: I have a lot of open tabs, and I'm usually working with the ones at the bottom of the list. When the bar minimizes the scroll position resets back to the beginning. So, every time I want to select a tab, I have to scroll back down, which makes this feature very hard to use.

Expected behavior: After the vertical bar minimizes, and I hover again, it should keep the scroll position.

I would be grateful for some information on container behavior, i.e. I created "permanent" (as opposed to temporary) containers for sites where I want that site's cookies & site data preserved in a container, so I can click "Clear Cookies/History" (or "Clear... when Firefox closes) and the items stored in PERMANENT containers are left alone, while all else is deleted. "Clear ...." doesn't appear to be respecting the permanent containers I have set up precisely to preserve these sites' cookies & data.

I'm not sure what the point of Permanent Containers is, if not to preserve those sites' data, for the sites' later use when you set Firefox to Clear Cookies and Site Data whenever Firefox Closes (or Clear Cookies & Site Data with one click). I expected it to respect data in Permanent containers, as exceptions. Else why not just use separate Temporary Containers for everything? Why bother with Permanent Containers if everything is going to be deleted when Firefox closes, whether it's marked "Permanent" or not? Is there a solution for this? Thanks, -AnneF

Scenario.

Open Firefox on Ubuntu Arm64 (Snapdragon X Elite, Asus Vivobook S15).

Open any page with scrolling.

Try to scroll page via mouse-wheel

Result: Firefox crashes.

Hello, using Windows Version 22H2 (Build 19045.5965), Firefox 139.0.4, Thunderbird 139.0.2, I can drag multiple emails from Thunderbird but not drop them into Firefox (the stop symbol appears and does not let me finish the action). However, dragging and dropping single emails does work. Firefox does not understand the imap address but the drop is registered which is all that is relevant to me. Is this a bug/missing feature in Firefox or a problem with Thunderbird and Firefox on Windows? Or is there a way to do it by simply adjusting (preferrably very few) settings? Dragging and dropping multiple emails using Thunderbird and Firefox on Linux Mint works fine. Dragging and dropping multiple emails from the Windows Explorer to Firefox also works fine. In testing, the issue only arose using Thunderbird + Firefox, Chromium-based browsers also worked fine with Thunderbird. If this is the wrong forum to ask such a question because this should rather be in a bug tracker or something similar, please let me know. If this should be on the Thunderbird thread instead of Firefox, also let me know. Thank you for your help.

Clearly your crappy browser system won't stop crashing my tabs with its stupid updates randomly out of no where while I'm in the middle of working on something. I can't even report bugs in games anymore because I go to pastebin to post a crash log, and firefox decides to say 'RESTART FIREFOX TO CONTINUE USING' for no reason. I am very angry, this happens so often its ridiculous. I have updates set to "check and choose" and yet your browser keeps crashing all tabs all windows telling me to restart to continue using, and only today did I realize it said it was related to an update. This is unacceptable behavior. This browser is becoming unbearable. Crashing/updating in the middle of my work is very bad, and this is getting old. Obviously this time it was an unwarranted update, who knows if my browser has even been crashing at all. Just keeps getting disabled for your forced updates. I need them disabled, NOW. I choose when to update. NOT YOU.
