Forum communautaire Firefox

Firefox comes up in a large window, covering most of my screen. I can resize the browser window just fine, as expected. However when I close the program, then open it later, the browser window is not the size and position it was in when I stopped the program last, it comes up with a large window again.

When using desktop Firefox 145.0 for Windows to browse the demo page of Logseq, the division/button to choose a folder on my computer is missing, and the following text is in place instead.

"It seems that your browser doesn't support the new native filesystem API, please use any Chromium 86+ based browser like Chrome, Vivaldi, Edge, etc. Notice that the API doesn't support mobile browsers at the moment."

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

Well, well, well. Latest Firefox update and what did you folks send along to take over my PC screen when I log-in? This: https://getadblock.com/en/update/latest/?f=f&version=6.31.1&u=68uu84zt49066849&bc=3072&rt=0

Clever, clever, clever aren't you folks?

1. I have NEVER downloaded "adblock" 2. "Adblock" cannot be found in the PROGRAMS listed on my PC, so no way to "uninstall" your uninvited, unwelcome, unneeded bit of buy-this-buy-this-buy-this angling. 3. "Adblock" cannot be found on a search of the registry. 3. What a pathetic approach, Firefoxers!

GET RID OF IT FROM SHOWING UP ON MY COMPUTER SCREEN WHEN I OPEN FIREFOX! NOW!

Hello, after ff updated, gray line appeared. It does not disappear after changing theme. I am using laptop and a monitor. On laptop browser window goes fully to the top, but when i drag ff to the secondary monitor, gray line appears. I will attach photos.

I have one particular tab group that stores a lot of tabs that I keep collapsed when not using them, because otherwise they clog up my tab bar. But with the new collapsed tab group preview, when I scroll along my tabs my screen will randomly flash with a full page of tabs, as there is no delay on the preview. I don't think this feature was designed with dozens of tabs with long titles in mind. The ability to have a delay on the hover effect, or preferably to disable it all together, would be much much much appreciated.

I was experiencing that one bug that locks the sidebar from opening on hover (even with the option enabled) and I was somehow able to change the size of the sidebar while trying to get it to start working again (IDK why I didn't just close and reopen my browser because I know that fixes that) and now my open on hover sidebar is the biggest it can go and it is genuinely unusable. I can't change the size of it while it's on the open on hover option, but changing it back to the fixed/static sidebar and then editing the size does not carry over when I re-enable the open on hover option. Objectively, this is really dumb and kind of hilarious. I know I am dumb for this.

Youtube does not work. It shows somekind of default page that is essentially blank. It does say: "Try searching to get started" and "Start watching videos to help us build a feed of videos you'll love."

But it will not respond when I attempt to search anything.

Since a month or so, Firefox browser freezes when playing youtube videos. Simply closing the app and restarting won't do the trick, I am forced to open the WIN Task Manager and manually "end task" before I can watch youtube videos again ... until an hour later, or lucky a day later, the same drama unfolds. I run the newest version of each, Firefox and Windows 11. No new extensions or plugins have been added recently. What is to do here? I'm since Netscape on this route and would hate to switch to another browser... :-) Thanks in advance!

i even deleted ALL my bookmarks............I cant get rid of the ribbon across the top, no matter how many times i try. And now I see, the bookmarks live on even after I deleted all of them yesterday.

I have been using Firefox for a long time without any problem. An update was loaded onto my laptop and now when I try to sign on through my iPhone when I go to menu, there is no selection to sign in. And as a result, I am pretty much dead in the water.
