Firefox Support Forum

After loading its most recent update, I am unable to open Firefox. I get two error messages. The procedure entry point SECMOD_LockedModuleHasRemovableSlots could not be located in the dynamic linked library C:\Program Files\Mozilla Firefox\xul.dll and a second error message couldn't load XPCOM. What can I do to solve this?

Hi,

so for 2 versions now (since 101.0.1, while 101.0 was still ok) everytime when I'm in the Library/Bookmark Manager and expand any folder on the left, in the main window with the bookmarks, it jumps to the very top.

That is especionally annoying when you've selected some bookmarks to sort into folders which you first need to expand.

Why was that change? That behaviour wasn't there in earlier versions; and also makes no sense.

Hello,

The issue is as follows: unless I use 'alerts.useSystemBackend = true' (which I don't want to do), I'm not getting any push notifications.

Using this test site: https://www.bennish.net/web-notifications.html - the logs goes as follows: Notification #1 queued for display Notification #1 closed

What I've tried: troubleshooting mode, reinstalling firefox, using a completely fresh&clean installation, and even reinstalling windows. Even after reinstalling windows and immediately installing firefox, the problem persists. However, it doesn't happen on another machine I've tested on, everything works perfectly there.

What could possibly be the problem? Please help!

Couldn't open Firefox XPCOM error.

Downloaded Firefox again and I now have Firefox in OS/Program Files/Mozilla Firefox (which doesn't work - XPCOM error) and a second version in OS/Program Files (x86) which works but has lost all my bookmarks and passwords.

How can I fix this please.

Hi, I've just reinstalled my firefox browser and I have some issues: - I can't install ANY add-on, even the ones from Mozilla Firefox itself, I get the message "Installation aborted because the add-on appears to be corrupt." on all of them - I can't add another language on my browser and get an error message "Firefox can't update your languages right now" - The screenshot option doesn't work, on any page

I have already tried deleting and removing all data from Firefox, and reinstalling it again but it doesn't work. I'm really at a loss with what to do.

Thanks

See dialog box screen print below. The .cpp file is not a GIT file. A .cpp file is a C++ program source file from Microsoft Visual Studio, and I should be able to open the file with Visual Studio 2019 (current version of Visual Studio on my PC). But misclassifying the .ccp file as GIT does not give me the option of opening the file with Visual Studio 2019. How do I change the classification of .cpp files from GIT to C++ (I'm on the newest version of Firefox...all prior versions worked correctly) ?

The Bookmark menu used to open with ONE click. Now it assumes you're using the same bookmark, and if you want a different one, you have to click twice. I have many bookmark categories, and I usually have to click twice to get to the menu to choose a folder/location.

I looked for but couldn't find an OPTION for it to work as it used to, open with one click. I'm disappointed that I couldn't find this option. I hope the option to return to the way it used to work will be available in the next Firefox update.

Hi there,

I have a problem. I had two windows with aprox 30 really important tabs each open at all times. Somehow firefox closed those two windows when I opened a third window (I don't know why and it doesn't matter tbh) and I didn't notice. I opened other temp windows and because of that the previous two with the important tabs were deleted from the chronic.

Is there any way at all to restore those two?

In my sessionstore-backups directory there are six files. previous.jsonlz4, recovery.baklz4 and recovery.jsonlz4. The other two are upgrade.jsonlz4 with a date at the end. The last one is from 20220630. Could this possibly be some older backup from my chronic with my old two windows? If so, is there a way to restore those? Just renaming them didn't seem to work...

I'd be glad for any help anybody could give me. :)

I suddenly can't click the "copy song link" item in Spotify anymore. It worked fine last week and works normally in Chrome.

It also fails in Troubleshoot Mode and after clearing Startup Cache.

Firefox 102.0 (64 bit) on Windows 10

This last update for Firefox was a bust! It has totally rerouted where my downloads go, changed all my settings! How do I go back to the prior version of Firefox? This has really affected my productivity. I need someone from support to answer this question, and I see I'm not the only one with issues.

Other than what i described above, i have submitted questions, and now FF is blinking ! This is a very unstable release!. Mozilla needs to retract this crap and work on a real browser update. I was prompted to update to 102, then after experiencing tons of problems, another update, to 102.1, which achieved....nothing at all.

What is going on with mozilla? this is crazy!

I cannot load lowes.com or homedepot using firefox. I get the following message: Access Denied You don't have permission to access "http://www.lowes.com/" on this server. Reference #18.1dfbda17.1656344082.168cca36 I have clicked on the padlock in address line and cleared all cookies however that only works one time and then back to same error message above.

I have been watching videos on paramountplus through firefox for over a year. Last week, they stopped playing at all. I can navigate the paramounplus website just fine and I am not getting any error messages, the videos simply don't start when i hit play. I spoke with support at paramountplus and they said it was because I wasn't using chrome as my browser. I did download chrome (reluctantly) with the agent on the phone and the videos played just fine. I have not made any adjustments to my computer or installed any new programing. Everything is exactly as it was when the videos were playing fine through firefox. Any ideas?

Hi I have a problem playing videos available on skynews.com.au where the white rotating dots within the black circle just keep rotating and loading does not occur. I assume this to be a result of a setting problem because it does not occur on another browser on my desktop computer.

Any advice?

When I open a pdf document from a website online, all colours turn violet. The original colour is just shown on the miniature view on the left side. Every time I open the browser again, there different pages shown with the original colour, but when I click on them they stay violet. When I download the document, it has the correct colour.

I have tried to change the colour setting for designs with high contrast, but there is no difference.
