Hi All,

I got my new laptop today and lost all of my bookmarks/setting/logins which were saved in Firefox Sync. Literally after logging in the new Firefox I installed nothing got restored. Is there a way to restore all this information in Firefox Sync? I desperately need them as it's related to my work. Thanks for any help Folks!

Hello there, Me and my co-workers are having trouble with Firefox RAM usage. After last update on every PC Firefox started to use too much RAM. Everyone has 8GB RAM and at least Intel Core i4 9th gen. What can we do to optimize Firefox? Is there any settings that will help with performence?

Firefox 105.0.3 crashes at startup on Windows 11 Family 21H2 (build 22000.978) French. Location: France. No error message. Firefox main windows appears for a tenth of a second and disappears. Same in troubleshoot mode (Shift+firefox.exe). The troubleshoot dialog box shows for a tenth of a second and disappears. No error message. No crash report generated. Device is an MSI GF62 Thin. Antivirus is Microsoft's Essential Suite. No Norton, Avast, AVG, Malwarebytes or any other security software is installed (checked in task explorer and on the disk). I got this on another old PackardBell laptop (Windows 10) with the same security configuration. Cannot figure out what the problem is. I have no clue whatsoever. Any idea?

This started a couple of weeks ago. I've cleared my cache, data etc and it still gives me the message " We are unable to access your Account. For further assistance, please call the number on the back of your Card" I have called American Express about it, but it is only a problem with Firefox. I can login on Chrome - which I do not want to use. Help??

I posted a problem yesterday and received an email from Mozilla Support asking me for information. I have NO IDEA how to find my original support problem to add comments - PLEASE let me know HOW to answer the Mozilla Support email (other than this way). Here is what I got in the email:

"I can replicate the issue in 105.0.3 and see that it works in Chrome. see screenshot What version of macOS? What version of Firefox are you running?"

My answers are: macOS Monterey 12.6 (put on a few days ago - upgrade from Big Sur) 105.0.3 (64 bit) - which is marked "Up to date"

So, I have the latest operating system for my MacBook AIr and the latest Firefox Browser and the display issue still exists.

I keep having display problems with one website in particular. I keep clearing the website cache, and it temporarily rectifies the problem, only to have it return when more data ends up in the website cache. I am clearing this cache several times a day. I tried closing and reopening Firefox, but that does not clear the cache, even though it is set to clear all browsing history upon closing.

I've experienced this about 4 times now over the past few weeks, at seemingly random intervals. This occurs on both my Mac mini and MacBook pro (both with M1), usually after browsing for an hour or more. Possible culprit - this seems to have only started happening after running a Snowflake proxy. Could this be the cause? If not, what else might it be?

I have selected a particular theme (Classic Marine Blue) which I like. However, when I click on an item that has a dropdown menu, the background color of the dropdown is black with white text. I prefer white with black text. For example, this happens with the Library item with the drop downs Bookmarks, History, and Downloads.

I've tried using Firefox Colors, and couldn't solve the problem with a custom theme.

I get it that this happens because the text color on most of the toolbars is white, which apparently triggers Firefox to flip to a black background rather than staying with the original white background.

I don't wish to change the theme. All I want is my black-text on white-background drop down colors back.

Any suggestions? Please help. This is really annoying.

i just last night switched to Firefox and i am loving it! the only issue i have is that YouTube does not seem to be able to go over 480p no other website has this issue (for ex twitch) and if this could be fixed i would never go back to chrome

Hello, I am using Firefox (105.0.3) on a Macbook Pro Mac OS 12.6 as a default browser. Every time I click on a link two firefox windows always open up. I can't find anywhere why that issue keeps popping up because I've used firefox nightly and haven't had that issue at all. Any help would be appreciated!

When my system crashes, the session that is restored is from some time back. I was wondering when Firefox stores its session information and is there any way to force an update? How can I insure that the new session is saved?

Here is a suggestion for you guys.

Instead of using whatever cache files you have for pinned tabs, why not put a pinned tabs section in bookmarks so we don't have to worry about something funny eliminating the tabs. Make it easy on the user and don't force them to look for session files copy/rename, etc. Be smart.

That the firefox auto-downloads cause browser/computer issues effecting usability until you install them is bad enough, but today's automatic download once installed has repeatedly locked up the browser and apparently there is no interest on mozilla's part to hear said feedback? Or is there actually some way to actually report a bug in a firefox update to firefox/mozilla?

I notice that I sometimes have as much as 14 Firefox processes running at the same time, even though I only have one tab open.

E.g. just starting up produces 9 processes, consuming some 43% of memory! I see no way to limit the number of process in Settings->Performance (ALL "solutions" to this problem involve changing the "Content process limit", but that seems to have gone in the latest Firefox version?) What do I do?

I've tried disabling all my add-ons and no luck. Cleared caches and ups-related cookies. Chrome resolves ups.com to https://www.ups.com/us/en/Home.page, but Firefox won't. If I type that full address it connects fine. Just ups.com gives a site timed out message (see image). Thanks, DougP

I have gone into Paddy Power website today in order to watch live racing and suddenly it is unable to load the live feed. Is there something I can do to get this working again please ? I attach a screen shot of what I am seeing.

Many thanks for any help you can provide
