Once a week or so, Firefox crashes unexpectedly. The popup indicates its alerting Microsoft of the crash, but apparently not notifying Mozilla.

Once such a crash occurs, I close Firefox. Reopening it results in a crash shortly after all tabs open and I click on something (usually 3 or 4 tabs are open). No matter how many times I let Firefox close and then I reopen it, the crash recurs. The only recovery is a complete reboot of my PC.

How can I get and submit crash reports to support in hopes of getting a resolution?

the top bar in the browser is so small it is hard to read and i find it difficult to access the icons. increasing the value of "layout.css.devPixelsPerPx" increased the browser text but did not affect the top bar. Is their another approach or is their a magnifier the will work. Thanks.

اینجا میتونی با جزئیات بیشتر بنویسی، مثلاً:

When I play YouTube videos in Firefox, they are constantly choppy and slow, even though my internet connection is fine and other browsers (like Chrome) work smoothly. This happens with both HD and lower quality videos. I've already tried clearing cache and disabling extensions, but the issue persists. Please help me fix this.

After upgrading to Firefox 140, the address bar no longer lets me quickly switch between search enginges using the up and down arrow. Is there a way to re-enable this?

Before, I could type the search term and then press the down arrow a couple of times to search with, for example, Wikipedia instead of my default DuckDuckGo. The new address bar no longer seems to include this behaviour.

I am logging in to my browser as normal, but am still getting the notification "You must log in to this network before you can access the Internet". This is cutting me off from regular internet access as if I was not logged in.

Firefox doesn’t spell‑check in Copilot because Copilot uses a modern custom text editor that Firefox doesn’t recognize as a normal typing area. Since Firefox never turns its spell‑checker on in this kind of editor, nothing actually fails, so there’s no error code or message. The spell‑checker engine simply never activates. For this to work, Firefox would need to update its spell‑checker so it can handle newer web‑based editors instead of only traditional text boxes.

I cannot access Fry's digital coupons - it always says: no coupons available try again later. Fry's customer service says it is my server not Fry's that is the problem.

Can you help?

I am on Windows 11. Asus laptop PC. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. This needs to change PLEASE.

According to my settings, Firefox should clear the cache completely. Bur it is never fully cleared, there are always about. 9.3 MB left at the temporary data. It should be 0 MB. Even clearing the cache "manually" does not clear it completely. HOW CAN I CLEAR MY CACHE COMPLETELY? (Firefox / Windows 11)
