Firefox Support Forum

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?

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

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?

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!

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.

You keep saying you fixed this problem and obviously you didn't. Firefox will not let me sign into starbucks.com. Keeps saying sign-in unsuccessful. Site works perfectly with safari.

I installed CLIO integration in my Outlook email and i use Firefox as my browser for my email and other online business activities. The integration worked well for a while and then there was an update and when I installed the update, I noticed the integration did not work anymore and I am unable to save emails like I could before.
