Firefox on Windows 11 - can't log into Yahoo Mail. No problem with Microsoft Edge, Chrome or Duck Duck Go.

I get the following message when trying from Firefox: "Something's gone wrong. We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over."

All other websites work on Firefox. I've already told Firefox to "forget this website". still doesn't work.

I have a different theme and cursor on my system. I would like to include them in Zen Browser. They are Candy Mac and Azenis respectively. There is no setting to do this. Many other browsers have System themes as an option.

I have noticed that recently, whenever I start Firefox, BING is auto-opening a new tab *without my input.* Firefox is not my default browser (I use several), and I have removed ALL extensions and themes (except for ad-blocking, which has always been there), and ensured that pop-up blocker is enabled. My Windows 10 PC cannot find any malware; I hate being hijacked (esp. by Microsoft) and want this to stop! My other browsers do not do this...only Firefox. I have tried suggestions to modify REGEDIT, but can find no solutions to prevent this (other than not using Firefox anymore). Help, please! Thanks so much.

Firefox has recently become unreadable--it is blurry, then clear, blurry, then clear. It has become unusable. I've moved on to Edge. After much research, it is apparent that this is a problem unique to Firefox, who hasn't bothered to address or correct this issue. No more Firefox for me:(

Desktop PC running latest Thunderbird and Firefox. Started Thunderbird, instead of the usual tabs opening, it appears to have forgotten my accounts, asks for my email address, i.e. starting from scratch again. Starting Firefox, all previously-open tabs have gone, though bookmarks are all there.

Has there been some update which has wiped or reset Mozilla data? Yes, obviously I can go through setting up Thunderbird again but that will take quite some time and yes, I can use Firefox but many of the tabs I had open were there for a reason and it will take a while to find them all again.

Is there any way that the previous state can be recovered? My laptop has both applications running fine and I have paused Windows updates for a week, just in case the latest update caused this. Thank you.

Hello! I have multiple issues with Firefox after YEARS and YEARS of usage.

1) There is always a problem logging into sites that require captcha. This started happening a few months ago. So sites will not open in Firefox, but there's no problem with using Chrome.

2) All of a sudden, when I open and download PDFs from websites, the documents are black. I've gone in and disabled dark theme, but that hasn't made a difference. Again, this is a Firefox issue because it doesn't happen when I'm using Chrome.

Hoping you can help me with both issues. Thanks much!

My gmail no longer opens on latest Modzilla update 135.0, although it still opens on Chrome or Edge. I can still access my Google account and other Google functions like Google One but my gmail does not load. I do not want to switch to another browser so I tried to clear cache, cookies, history but it did not work either. I also tried to open my gmailin private browsing mode but it still did not open.

Please tell me how I can remove this message. I have never seen it before and now I cannot read e-mails after 8/2/25 (I have been away for a few days).

I have tried to send myself a test message today but it will not go. I have tried cleaning out my mail server mailboxes but this has no effect. Running anti-virus software has no effect either.

Any help would be appreciated,

Thank you,
