If I copy and paste any two words or more into the search bar on the new tab it goes to google.co.uk as that is set but only searches for the phrase minus the first word. If I paste it into the address bar everything is ok. If I do the same with a one word term the search bar does nothing having "lost" that word and the address bar works fine.

The tab under Inspect Element -> Inspector -> The column right beneath filter styles column has this feature that suggests you some css properties. On my browser they get filled in more than once, endlessly I might say (without me pressing any button). This makes it very hard to add any css styles and I'd like to know how to stop this behaviour.

After updating to version 94.0b9, the program began to slow down terribly. This is especially pronounced on YouTube: you select a search, enter a request, open two or three tabs from the proposed one with a possibly useful video ... That's it! You can go to a cafe for coffee and rolls. It became impossible to use the browser.

How to roll back to the previous version of the program?

In my "saved addresses" list under the Privacy and Security section of Firefox Settings, there are two addresses of people that have never used my computer. One formerly went to my school, and the other is a stranger. I can think of no way that they could have had access to my account at any time. Are there any other possible explanations for this?

Hello,

I am a Web Developer, fixing a website for my client. After the page is cached in Mozilla Firefox the layout breaks, when I clean the cache everything is back to normal. This issue is only present in Mozilla Firefox, I don't have that issue with Google Chrome.

Website URL: https://www.impeccablex.com/ Please see the screenshots attached, you can see the layout before and after.

I have tried almost everything that I could think of, don't know what to try next. Any suggestions?

Thank you in advance! Best Regards, Mario C.

Until recently, when I started typing in the address bar, FF was offering suggestions that were clearly based on addresses I had gone to in the past and seemed remarkably prescient about where I wanted to go. For example, if I typed the name of my hosting service, Seanet, one of the top 2 or 3 choices would be Seanet's login page.

Now, if I type "sean" for example, I get a bunch of irrelevant stuff ("sean connery") and about 10 lines down, it says "firefox suggests" and one of those is the login page. I ran into an article talking about how to change settings under privacy/address bar, but those don't affect this behavior. They change what might be the source of suggestions, and I limited it to browsing history, and that didn't help at all.

Maybe this is something that can't be fixed, but things were easier when FF listed very near the top the actual addresses I went to. Not all have deteriorated, e.g. (to reveal stuff about me) typing "x" gets xkcd.com as the first suggestion, and typing "e" gets explainxkcd.com as the first (sorry, sometimes I don't get the computer references and need an explanation).

Any help would be appreciated.

After I take a screenshot of the whole screen or a part of the screen on Windows, it goes to the clipboard. But when i paste this screenshot in websites, it appears in a bunch of coloured stripes, like a broken TV screen. What's the problem?

Somewhere between firefox developer edition 80 and firefox developer edition 94 a bug was introduced that results in firefox showing a huge list of possible public domains for an email address that i'm trying to enter.

Firefox should only show values I've entered previously. Instead it shows garbage such as gmail and yahoo as shown in the picture.

How do I wipe the list that it's using so that it never happens again?

I'd swear that I used to be able to click on an animation/video/gif to stop at looping, but I cannot stop this one by doing that:

https://d2rdhxfof4qmbb.cloudfront.net/wp-content/uploads/20190129121540/facts-min.gif

It must've been one of those custom settings I had before I got the new computer and ran a clean install of firefox.

I have set media seamless looping to off in about:config, but I can't see what other preferences would relate to this.

Hello, Since my last update, Firefox 93, my bookmarks present a huge line spacing between them, line spacing that I would like to control to see more bookmarks at a time. Do you know how to proceed ? Thank you very much.

I have been using the FF dark theme for a while now and am used to it, but I do not like other websites dark (for example youtube, ietf documents, etc.) and suddenly firefox has started showing them in dark mode as well. I have tried to search for a fix for this with no success so far. What I have tried so far: set ui.systemUsesDarkTheme to 0 set browser.in-content.dark-mode to false

Please help me disable Firefox requesting dark websites while I still use the dark theme itself. Regards.

I noticed the toolbars had changed positions and thought I'd use the customize page to see if I could reorganize them. Somehow I ended up with the usual three toolbars, but bookmarks are on the top (tabs) toolbar, not the bottom (bookmarks) toolbar, which is empty. This is Ubuntu 21, firefox 95.0b2.

Top: Starting on the far left are the Ubuntu window controls, my bookmarks. and tabs. Middle: The customized URL/search bar. Bottom: The bookmarks toolbar, which is empty. I know this is so because CTRL-SHIFT-B hides and shows it.

I can drag bookmarks on the top(tabs) toolbar around, reorganize them, and and delete bookmarks and folders, but always only on the top (tabs) toolbar. I cannot drag any of them to the bottom (empty bookmarks) toolbar.

Great news about Firefox being added to the Microsoft Store. It seems to me that method of keeping Firefox up-to-date might be more effective than the traditional Mozilla background service. However, I use the Beta channel. Is there any chance that channel will be added to MS Store? Regardless of the version I assume that you have to completely uninstall the conventional Firefox install and lose all your about:config and other settings (anything not included in Sync).

So, certain web pages apparently have text in white font color while also using a white background. I'd blame it on the team behind the page, but it seems that it works well on Chrome, so I'd like to know how to fix it.

I'd add images, but they take way too long to upload

Hello, I have issues with Firefox developer version for couple months now, when I play videos, like youtube, or other sites they constantly lag. They play for like 1min and lag, continue for another 2min then lag etc etc. (even short videos on twitter lag). It was not like that before and I don't have this problem in other browsers. Does anyone know what can be the problem here? Thanks

Hello! I am in a work environment and I am trying to determine if there is something in our security systems that is preventing Firefox from running properly. Once Firefox is installed, it works the rest of the day with no issue but almost daily the morning after, it will start to open then instantly crash. When I check the crash logs, it shows in most of them: Modules - Filename: umppc14210.dll Version: 6.28.14210.0 Debug Identifier: B9143DE260194C88AB48EFD6782C9EAF1 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

When using the dark theme from Firefox, Google searching seems to break completely as well as some pages will not load which may be related to this.

I have already tried uninstalling Firefox, deleting all of the folders, then reinstalling with a freshly downloaded installer (Even tried the beta one) with same results. It seems potentially MAYBE related to how long ago I closed Firefox before I shut down (Like Firefox is trying to save something to a secure location and times out, then it will work but if it hasn't timed out, then it crashes... or this is my guess)

The Signature seems to change randomly for the crash between crashes.

I really am tired of constantly reinstalling Firefox but I do not want to use Chrome or Edge unless websites require it.

I used Apple Migration Assistant to move the entirety of my wife's old iMac (the old computer won't accept updates, so her machine was not secure) to a new one. The migration operation appeared smooth and essentially perfect.

Somehow my Bookmarks have overwritten my wife's (years ago, I turned Synch = ON, was that it? Synch is OFF now). The bookmarks are still OK on the old computer, so how do I locate and move that info to the new machine "AND BE SURE TO GET IT RIGHT"? My wife is the family business manager, so her bookmarks are Insurance, Banking, Healthcare, etc.

I've done some searching, but there are thousands of posts, I can't wade through all of that.

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95
