I'm having a problem using my bank website with Firefox - I get a message when I move from one page to another, and that message closes the bank website - Here is the message: "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." It is very important to me to be able to view my accounts and investments daily - please help me solve this!

Hello! When I try to log into my Microsoft 365 Outlooks, I get the following message:

'Your browser is a bit unusual...

Try disabling ad blockers and other extensions, enabling javascript, using a different web browser or turning off your VPN.'

I did go in and turn off the ad blocker. I do not have a VPN, and I could not find anything about Javascript on the Preferences page.

Please let me know what to do so I can log into my email.

Thank you! Christine

New version produces "Access Denied" when logging into Chewy.com Please fix this. I tried to add an image, but, like last time, doing so froze the page and I couldn't get back here. Had to start over. Can I revert to the earlier version of Firefox that worked? If so, how?

Every time I try to login to a different page my firefox crashes.

I also did get the attached message, wasn't forsure if this was apart of the issue?

I have tried to dump the preferences, clear cache, restart, clear history.

As the subject says, certificate exceptions added "permanently" in the Certificate Manager are dumped at various intervals. For example after updating to 113.02, my certificates for a local router and switch were gone. Sometimes the certificate exceptions seem to be removed at random intervals. Can't really nail down what causes this but the "permanent exception" is not honored. I added several certificates a few days ago, now they're gone.

This has been an ongoing PITA for the past year or more. Why does Firefox make this so difficult?

I have a 2020 Mac Mini with Ventura 13.2.1 on it. I have four virtual desktops which are part of the OS. I place various apps on the others like stocks and weather etc. to diminish clutter on screen. Firefox shows up on all 4 of them. I want it on only one desktop. Safari works on only one and doesn't show in the other 3 desktops. I have searched the net but haven't found anything that speaks to this in particular. Thanks for any help with this and I hope it's just a simple setting. Regards, Jim Stephens

I am using Firefox Developer Edition in a work environment that only saves directories between weekly restarts by explicitly managed rules. As a result of some missing folders from my weekly restarts, I need to sign in to my Firefox account and enable sync each week. Currently my machine retains the %APPDATA%/Mozilla and %LOCALAPPDATA%/Mozilla directories + children.

What other directories are needed by Firefox Developer Edition in Windows to retain the user profile/syncing, et. al.?

Thank you for your time!

Hello. I run Firefox as my main laptop (Mac) browser. I have added Zotero to manage my writing reference citation library, and have downloaded the current Zotero Connector for Firefox. I should be able to add references from online, by using the Zotero save icon that should appear on my Firefox toolbar. But this icon is nowhere to be seen and I cannot see how to make it appear. The whole advantage of Zotero for me as a writing academic is pinned to this function, so I am anxious to get it working. How can I get the Zotero save icon in its proper place on my Firefox toolbar, just to the right of the search window? Many thanks

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

I have noticed in the last few days that Firefox is keeping my Mac from sleeping. This seems to have started around the time of updating Firefox to version 113.0.2 which happened 4 days ago. Any thoughts on how to debug this?

I have passwords stored in Dashlane. 1. Would i be anymore secure if i followed your prompts and disabled Dashlane in order to use Firefox relay; 2. If i disabled Dahlane to use Relay would i loose all the passwords saved in Dashlane?

Hi friends,

do you know any way to set a policy in the policy.json file to remove the "Import bookmarks" and "Getting Started" buttons that appear in the Bookmarks toolbar?

Thanks in advance!

One of my folders is lost. I know the bookmarks are in bookmarks as I can search on one or more. However, I can to know what folder they/it is in. Example: folder FOOD is lost, but I can search on hamburger and it shows up. etc. A one by one search takes a lot of time. I would like for the folder to show up in what other folder it is lost in.

This problem is getting worse all the time. Seems like each upgrade it gets worse. I shut down FF expecting it to restore all the tabs when restarting. But... Gone. Currently Mac OS 13.3.1 (22E261) FF Version: 113.0.1 (64-bit)

Is there a security setting that allows me to show all my passwords rather than having to toggle them on each time?

I am a recluse. There's never anyone looking over my shoulder. I just don't want to have to mess with it anymore.

If there isn't, could some kind developer please make an add-on?

I am using two computers: an iMac (late 2009) running 10.13.6 (High Sierra) and a Macbook Pro (13-inch, 2012) running 10.15.7 (Catalina).

Thank you!

If I recall correctly, there was a Firefox update several weeks ago. Since that time, there have been at least three occasions where a URL I manually enter initially takes me to the intended site, but is interrupted immediately by a message, such as "Checking Browser." This quickly disappears and I notice the browser begins accessing other pages in rapid succession, until I closed the window (in the attached screenshot, the browser history is in reverse chronological order). Never experienced anything like that in my 28 years on the web. What might be going on? Thanks.

Firefox uses around 1 to 2GB of RAM and around 25% of the CPU with just around 10 tabs open along with a YouTube video. A chromium based browser on the same system and the same tabs open uses around 400MB of RAM and around 10% of the CPU. Safari with the same tabs is even more efficient

I have tested this with safe mode, on another system with the same hardware but couldn't find what's causing the problem. I have uninstalled all dynamic themes as well.

Firefox does not use this kind of resources on windows or linux but uses something more close to chromium numbers (tested on a desktop PC, AMD Ryzen 3 3200G)

While I do not expect Safari levels of optimization, this problem only arising on Apple Silicon Macs is a problem worth solving. This is the only thing that's keeping me from using firefox as a daily driver and supporting the open web.
