I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

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.

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.

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.

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

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

Usually I just open firefox, and this opens one browser, and then all of my previous browser, and tab reopen, but this time firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tab, but it didnt.

After following the usuall firefox help giudes, it still wouldn't re open my previouse sessions. Now if I ask it to open my previouse sessions, it just opens the recent help giudes, and not anything before the crash.

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

Hello,

I was editing a fillable PDF document in Firefox, which I had saved repeatedly (saved over existing file) as I was making changes.

After a crash, I selected "recover session" and the document was open but was now empty. Another document I was editing, which was not open in Firefox but was being saved to a separate file, did not experience the loss of data entries.

Would anyone happen to know the reason for this issue and whether there is any way to recover the data?

Thank you.

Hi Mozilla - I just wanted to report some recent phenomena. In the past couple weeks Firefox, and related Private Browsing browser, seem to have developed consistent hangups in fetching data across a pretty wide range of sites. Both my banking sites will not load after logging in to them, just spins and spins. Also some very general searches will not load any results for minutes at a time, I just give up and kill them. I've uninstalled/cleaned/reinstalled latest version, etc, etc. By comparison, these same data fetches in banking sites, etc, work dandy in Duckduckgo browser, which is also a heavy no-trace browser. This ominous to me as I really like Firefox and do NOT want to have to resort to Edge. Duckduckgo browser is very good but doesn't have nearly the menu or favorites sort of features that Firefox does. Can you investigate? This is typical Win 10 system in Lenovo i7, been working like a champ till just recently, no system changes. Thanks.

How to prevent Firefox from opening links in a non-default container

I'm using the Firefox Multi-Account Containers extension and it's great. I have a number of containers manually created and use them according to my personal preference. No sites are associated with containers via settings, it's always manual.

Among those containers there's one I use for all things Google (Gmail etc). Which was great, as it allowed me to use both my personal Google account and G-Suite integrated with the workplace's SSO by simply using a default container for work stuff.

I updated Firefox to version 127.0.1, after which I discovered that clicking on Google Docs links in external applications now opens a tab in that custom container I created for my personal use. Which is clearly inconvenient, as most Google Docs links I open are work-related, so my personal account has nothing to do with them. Opening same links from within Firefox, e.g. by clicking on a bookmark, still opens a default container tab.

As I mentioned, there are no explicit association between Google links and that container, the "Limit to designated sites" option is switched off.

Is there anything I can do to revert back to the old behaviour, which is opening every external link in a default container?

I using an ASIS Latop model X756U running the Windows 10 Operating System. Firefox is my default browser.

I installed the Opt-Out Google Analytics Extension on 9 June 2024. The intent was identify which of my applications are using Google Analytics by testing them and seeing which ones were broken.

Having done that I removed the Opt-Out Google Analytics Extension from the Firefox Extension list.

Unfortunately the extension remains active and continues to disrupt my browsing experience.

How do I remove this extension permanently?
