When I went into my email this AM, a line above it stated that my browser no longer is supported. I have a desk-top MAC OS operating system and I have used Firefox to get into my email for a very long time. What gives? Thank you.

firefox removed my bookmarks and they had no right to do so. This upsets me big time, and like everything else they have no phone line to cll for support. firefox is a real pice of work.

On a certain bank site when making payments you go through the process setting them up and then when you go to confirm payment the banks screen goes grey. I use the same format for other banks. help please.

My computer automatically restarted, and when I reopened Firefox it was updated and my account was logged out. Once I logged in, everything was gone -- bookmarks, history, extensions. The only thing not gone were my saved passwords (so I know I logged back into my same account). I swear I backed everything up after the last snafu, but now I can't find anything. How do I fix this? I had 4+ years of bookmarks saved, plus my article saver extension.

zen_browser has this feature which I use multiple times per day every day: keyboard shortcut ´shift+cmd+c`to copy current URL to clipboard.

This is such a useful feature. It helps me save time and speed up my workflows a lot, so much that it's absence in Firefox is preventing me from going back to Firefox.

The feature was implemented in v1.6b back in early 2025 in zen_browser.

在 Firefox 内部：

通过 JS 触发的新页面 通过 a.click 触发的新页面 甚至 rel=noopener 都会被标记为：

“related browsing context”

进而共享同一个进程，新页签因为内存占用过高，导致旧页签卡死。

通过设置

1. 添加 COOP 响应头 add_header Cross-Origin-Opener-Policy "same-origin" always;也无法解决

设置空白页再重定向也无法解决

I cant sign into wellsfargo.com with firefox, I CAN sign in with my Avast browser. I have turned off enhanced protection, cleared cache and cookies, restarted my computer. I have called wells fargo and they have informed me that they cant see the sign in attempts and that no blocks to my account were there.

My Windows 11 computer crashed recently. Before restoring windows I was able to backup some data files. I thought that I had a Firefox backup, as I recorded a folder called “Old Firefox Data” It contained a Folder called “2eguguhi.default-release” of size 751 MB. It in turn contained 7,708 Files, & 2,269 Folders. When I re-started Firefox on my “fixed” Windows 11, It was a virgin with no History & no Bookmarks; my old configuration was lost. I tried to follow the advice Fro Mozilla Help But to no avail. It was not able to detect or recognise the Folder in “Old Firefox Data”

Am I Lost or can someone Help please.

I am running Windows 10 on a desktop pc. I have Firefox for Windows 148.0. I am editing a website on Joomla 5.4.3. To edit pages in Joomla, I use the TinyMCE editor. Since today, whenever I open a page in the editor, the editor keeps reloading constantly which renders the editing impossible. After I close the editor, the browser seems to lag for 5 to 10 seconds, before returning back to its normal, problem-free behaviour. This behaviour is only happening in the Firefox browser, not in others on the desktop.

I switched to my Macbook, which still had Firefox for iOS 147.0.4 running. There the above mentioned behaviour didn't occur. But when I updated Firefox for iOS to 148.0 the behaviour did start to occur.

So, I guess it is a bug in version 148.0? How can this problem be fixed?
