Kept getting messages that Firefox is unresponsive during use. Has now stopped all together. Uninstalled and reloaded, got a welcome to Firefox message then it went unresponsive again. Now a double click on the App to start does nothing.

I want to clear the cache on this laptop that has been in storage for months, but I can't get the instructions question lines to respond when I check the boxes ??? What am i missing?

I followed directions for "Secure Connection Failed" and I still get the screen when I reopen the email account. I went to Avast, Settings, Protection, Core Shield, Configure shield settings-Web Guard and unticked Enable Https Scanning. I hoped by following the directions found on your website the problem would be resolved. Now What do I do to get into my email account?

I am using Firefox 155.01 on MacBook Air (M1).

I updated to OS 27.0 yesterday.

I have tracking protection set to Standard (same as before the software update).

Websites I need to use frequently, such as my health care provider, just twirl, will not open.

Hi,

I'm using Firefox 155.0.1 64bits, in Linux Mint Debian Edition 7, x11, XFCE4. I have a Belgian keyboard. I have noticed that the dead keys aren't working any more when typing text / messages from within Firefox. I don't have this problem in other browsers or applications.

I used xev (x11 utility) to check if the dead keys were working and tested a different keyboard, all work. I tried to start Firefox in safe mode or by starting Firefox from a terminal with the following commands: - env GTK_IM_MODULE=xim firefox - env GTK_IM_MODULE=ibus firefox

But nothing worked. The dead keys aren't working. The issue must come from Firefox for it is not an hardware issue (tried different keyboards) nor software (dead keys work in other applications).

Any idea to fix this ?

Hello, hope your day is good. Since the internet wide announced date in mid June ;; where Microsoft made bios changes which blocked 3rd party vendors programs from fully connecting ,,, my laptop has not been able to ( run) Firefox ,, with out problems . Even to point where my laptop,, locks up . This summer of 2026 has been the worst computer stability issues ever. I’ve been forced to constantly hard stop my rig , spend hours with rebooting ,, and then using Revo to delete non MS apps ,, then download apps ,, especially FireFox Is there a permanent fix to get around the deranged tyrants at MS . Thank you

I've seen this on a few sites and it sounds like this person also experienced this. It happens on Linux and Window. I don't think it's a new bug/behavior.

I'll use vanguard.com as an example.

1. Visit investor.vanguard.com site. Click that you'd like to log on. 2. I'll be placed on a login.vanguard.com page that displays a Username field and a Password field. Because I've logged in before, those fields are yellow and filled in with the proper values. (In the case of the password field, it's all stars, but when I click to reveal the password, it's the correct password.) 3. Click on the "Log In". 4. The browser rerenders the page claiming that the userid or password is wrong.

But if I follow the above steps, but add a step:

2.5. I slightly edit both (one is not sufficient) fields, removing a character and putting it back in so the values are edited but not changed. As I do this the fields become white instead of yellow.

Now when I reach step (4), I'm actually logged in without complaints.

The underlying AJAX request is pretty cryptic, so I can't quickly spot/debug what happens at that level, but I assume the page is not passing the field values visible as yellow. on the page.

Am I misunderstanding how the yellow auto-fill works? (On most sites it works as I expected and no reediting the autofilled fields is necessary.)

Can this be fixed or should I put up with it?
