I had to do a refresh of Firefox to its default settings and have the copy of the old data folder sitting on my desktop. How do I restore it back to the state it was before doing the refresh ? Does this also restore the automatic login for sites where I had checked the "Remember Me" button on my initial login?

Hello.

Has the profile logic been thought through?

When I set a default profile, I would expect

A) all new pages open into the default B) That firefox always opens the default without request.

This does not happen.

firefox.exe -P is set correctly.

Any ideas? I feel after the profile choice was improved, the basic logic may of been broken.

Thanks

Good evening,

I was trying to use the VPN option on the Fire Fox browser and it will not let me use it. I press the get started tab, sign in, and when it asks me to turn it on it simply just shows me the get started window again and it doesn't change. Is there anyway to fix this? Please let me know.

Thank you,

I've been using Firefox for so many years I don't use any other browser unless a site doesn't work,then I use 'Opera' (very infrequent). I updated Firefox to v154.0 and now searching does not work properly.

I used to be able to enter a question into the bar/box where one would normally view any given URL, select return, and Firefox would bring up Yahoo! search results.

With this update, that doesn't work. When I select return the URL that had been in the space just reappears. If I visit the Yahoo! main page and try to use the search box with the magnifying/eye-glass, it launches a blank tab.

I'm forced to use the AI icon to get a search result. I do NOT want to use that feature.

Also, with Firefox 154.0 I cannot remove other search engines. With every update I remove Google, Bing, Duck-Duck-Go, Wiki, Amazon, etc. because I ONLY want one search engine, Yahoo!

I checked the Yahoo!Search Extension and made sure all the "allow" buttons needed were selected.

I want to remove the other search engines from the Settings tab, and I would like to have the same behavior prior to the update: simply type my question or text into the main html bar/box and select return, and get results.

I see that other had an issue starting with version 142 or so that was similar, but I've not had this issue until two days ago.

Any help is appreciated. And yes I delete my cache etc. regularly. I'm on Mac OS 15.7.7 and again, it has never been a problem until updating Firefox to v154.

Cannot reach extensions search from Firefox about:addons page. I keep getting the following when I search for any extension.

Error 503 Backend.max_conn reached Backend.max_conn reached Error 54113 Details: cache-bfi-krnt7300022-BFI 1787247272 698900040 Varnish cache server

Firefox lately seems to create problems every time it is updated. I am really leaning towards making MSEdge my default browser because I am tired of these problems cropping up at each major update. I spent several hours this morning making sure my bookmarks and my saved logins and passwords were up to date with what I have in Firefox plus making sure my privacy and security were at it's tightest and strongest there. Major updates for Firefox use to go smoothly and seamlessly but that is now questionable.

Respectfully

Since yesterday, I have been trying to access www.old.reddit.com - which I have been using for 15 years and is a much better version than the new one they introduced several years ago, reddit.com?

I keep getting "The page isn’t redirecting properly

Firefox can’t connect to the server at old.reddit.com"

What is going on?

The keyboard shortcuts (CTRL + T to open new tab) are not available on Firefox 154.0. Also, the right-click option no longer displays standard options ie "save image as..." Image below is after right-clicking on "show details" link, after text "We've made some educated guesses about your current browser and operating system."

I have had a bit of a problem with a keyboard today and tried downloading drivers and reading faqs about it, and apparently as of today (august 20th 2026) firefox decided that most sites are unreachable (which they clearly are since the laptop running win11 works) Why the sudden overstep? BTW I can't access this page on the win10 computer.

After the last update I keep bein forcefully logged out of my firefox account. And when I manage to log in, my saved passwords are all gone! After restarting firefox I'm logged out again. What's going on?

Every time I open Firefox I get the prompt for my master password even though I'm not on a website. How do I get this to stop? It has begun to ask me twice and only does it once if I disable sync. How do I get it to stop unless I'm actually trying to sign in to something?

Recent update nuked all my custom containers, and closed every page that was currently open within those containers (pretty devastating bug).

Now, I go to add sites to the new custom containers I made to replace the earlier ones. When I go Manage Containers > pick a custom container > "manage site list ..." and there is no list. Just a blank window.

Copying this from a Reddit post as I have the same issue and looking for a solution:

Recently in the past month or so, the Del/Delete key has stopped working in Firefox's Save As dialog box popup. Literally every other key works fine system-wide, and Del works in everything but Firefox's Save As box.

To elaborate... Opening up the Save As box for anything in Firefox—a page, a file, an image, etc.—and trying to use the Del key to delete characters in the filename field just doesn't work. Backspace works fine, all other keys work fine.

The only way to get Del to work in that scenario is by pressing Shift+Del instead, which is odd because it didn't used to be like that.

I know the obvious answer is "Just don't use the Del key to edit a filename when saving files in Firefox" or "Use the backspace key insted", but I've been doing it this way for so long that it's pure muscle memory at this point.

I've tested/confirmed that the Del key stops working this way in regular Firefox, private windows, and troubleshooting mode, so I don't think it's an issue with addons or extensions. I can't pinpoint anything else on the system that might be causing it either; it really does seem to be an inherent Firefox issue that's suddenly popped up.
