Firefox Support Forum

trying to restore previous settings i have accidentally created multiple copy's of bookmarks and folders. many have more than 10 copy's and i now have over 400 000 bookmarks. is there any quick way to delete the copys of bookmarks?

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

In Firefox, after a reboot, how can I re-open my previous sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previous sessions.

Usually I just open Firefox, and this opens one browser, and then all of my previous browser, and tabs reopen, but this time Firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tabs, but it didn't.

After following the usual Firefox help guides, it still wouldn't re-open my previous sessions. Now if I ask it to open my previous sessions, it just opens the recent help guides, and not anything before the crash.

So is there a backup file of my missing sessions that I can roll back to?

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

Firefox, like most browsers, is full of jargon and terms which are never defined. So, for a new user, what should be simple become complicated. Developers obviously thought that everybody understands, but it is not true. It would be helpful if there was a term definition for each term and symbol used. I find my self in a kind of rabbit hole when trying to do things, and even when I ask for help, there is no term definition help.

I can't open Firefox browser. I get an error message, "Error: Platform version '127.0.1 is not compatible with minVersion > = 127.0 maxVersion < = 127.0"

I can only get Google Chrome.

Please advise

Corel asked me to do a screen shot of the issue: Attached When I look at the changed screen, There is an icon infront of the Web address line that looks like a robot. When I rollover it this statement comes up: Browser is under remote control reason (Dev Tools) All of the address bar is inpink. I copied it but color does not copy. when I did the screen shot the address line is not copied. https://support.mozilla.org/en-US/questions/1449321?utm_campaign=questions-reply&utm_source=notification&utm_medium=email

daThis is still frustrating. I do not like to use the browser when something else appears to be in control. I have MacAFee and run a scan but nothing shows up? If developers are following my browser, I should beable to turn this off.

When I used to take screenshots, they would be automatically named with the date, time, and part of the text captured regardless of language. A few days ago and with no reason I can discern, it now saves any non-English screenshots with something like this "Screenshot 2024-06-23 a[...].png" instead of "Screenshot 2024-06-22 at 08-02-28 Politics Policy Polit[...].png" (usual for English text and what I used to get with all languages).

Which means I have to manually rename screenshots. Does anyone know how I can fix this because I am working on a project with lots of screenshots for topics from different languages?

I would like to create bookmark folders WITHIN a bookmark folder. Example: I search the American South, so I have a SOUTH bookmark. But within that bookmark, I would like to have a subfolder for each state. Please help!

Every so often while browsing, for several FF versions, now, hover card functionality on some sites will simply stop working, even after a complete browser restart. Eventually the cards come back on their own.

Not a crucial issue, frankly, but an annoying one, and I'd like to know why it keeps happening and what can be done to stop it.

Hello, I'm a web developer. I'm using the Firefox Developer Edition and currently working on a project that requires caret manipulation. I have this function right here that fetches the caret's client rect: ``` function getCaretRect(): DOMRect | null {

 const sel = window.getSelection()
 if (!sel || sel.rangeCount === 0) return null

 const range = sel.getRangeAt(0)
 const rects = range.getClientRects()
 if (rects.length === 0) return null

 return rects[0]

} ``` Here is where the issue arises. Suppose I have a contenteditable div with two line breaks (no new lines), and the second line is smaller than the first one. If the caret is positioned somewhere that is further than the end of the second line, and I press the down arrow key, then left, for some reason the caret rect I get has all values set to zero, like this: `{ x: 0, y: 0, width: 0, height: 0, top: 0, right: 0, bottom: 0, left: 0 }` I will add an image to explain further.

I don't have this issue on Chromium based browsers, but cross browser support is important for me.

There is one more issue to do with caret manipulation which is how contenteditable divs are handled. On a Chromium based browser, if I have a parent div that's contenteditable, then another div that's not contenteditable (contenteditable="false" explicitly), then two children divs which are both contenteditable (or more), I can navigate through the divs freely using the arrow keys and focus is managed better alongside event handlers. This is not present on Firefox, however.

If this is not the right place to ask for help then please guide me where is more suitable.

It started this morning (6/23/24) the page for a YouTube video will load but the video doesn't play. I have cleared the cookies and cache, shut the browser down, restarted the computer, turned off all the extensions, and have turned off hardware acceleration. Nothing has changed, I can watch other videos on Firefox and Youtube work as normal on other browsers. Last night (6/22/26) before shutting down may computer for the night I had an update for Firefox and shut the browser so it could update. The image is of what the video section is displaying.

Is there a way to set a separate theme for the private browsing option? I like being able to visually distinguish between the normal browser and the private one, but enabling a theme seems to set the same visuals for both.

If separate themes are not a thing, perhaps they could be added in a later update?

Thanks for all your time and effort.

Ive tried everything under the Sun to try to get rid of that Annoying ( Sign in with Google) out of my computer but nothing works ?? Is there a solution ?? I cannot open most of my Sites with it there !! Anyone Please HELP !!

After uninstall and reinstall my Firefox i can't restore my bookmark. I used (CTRL+shift+b) and restore my file "JSONLZ4". But i have an error as "Unable to process the backup file". I read your forum and test many things but nothing. I also used the https://www.jeffersonscher.com/ffu/bookbackreader.html,but it does not work? It prompts:failed JSON parsing: SyntaxError: Unexpected end of JSON input. I really need my bookmarks! How can I restore them?

Hi,

my firefox does not load any webpage no matter what Firefox profile I am using (created a new one for tests). I have a Win10 pc with Avast and Comodo installed, the system with the mentioned software and multiple different Firefox profiles was running since several years without problems.

A month ago I had the same issue with Firefox 126, which I guess was caused by a windows update, where I had trouble getting it installed. But after this (I had to increase the system reserved partition) Firefox was running without any problmes like before ...

Now no pages kan be load and always the crash monitor pops up.
