Hardware: iMac 5K, 27-inch, 2017 macOS: Ventura 13.2 Firefox: 109.0.dmg File Type: Disk Image

For an unknown reason my Firefox browser locked up in the middle of a session. A full system re-start failed to fix the problem – all other software Apple Safari, Adobe Lightroom & Photoshop and Microsoft Office etc. continue to work as normal. Both Bitdefender and Malwarebytes full system scans have failed to identify any security issues.

To remove any possibility there was a macOS issue I successfully recovered the operating system from the mac in Recovery mode.

As the Firefox app would still not respond to the normal app opening process I removed the failed app from the mac “Applications” folder using the AppCleaner app and downloaded a new Firefox app file from the Mozilla Firefox site. I then dragged the downloaded file to the mac “Applications” folder and while holding the control key Ejected “Firefox” from the menu - the “Firefox” named disk icon on the mac screen and showing in the Finder “Locations” disappeared. Following this I successfully dragged Firefox from the “Applications” folder to the dock.

When the Firefox icon in the dock or in the Applications folder are selected the error message appears: The application “Firefox.app” can’t be opened. Repeated deletion of the Firefox app from the mac, restarting the mac, re-downloading the Mozilla Firefox app etc. etc. has resulted in the same failure. In the interim I am using Safari for the web but want to resume using Firefox asap due to Safari’s limitations.

Am I missing something in the Firefox installation procedure or there is an unrecognised security bug in the system? This is the first time I have had any issue arise with a Firefox installation process on either Windows or Apple systems.

Grateful for any advice.

I had a version of firefox working. The world was sweet.

One day (1 July or there about) things changed and firefox was basically useless. When I load it, all logins are forgotten and I have to log in again. (Painful, and another thread)

That aside: The "new" version was 102.0 This was applied to my machine without me knowing. (This also happened on another machine I have but luckily it didn't suffer the same problem.) But anyway...

The machine now has 102.0 installed.

The other day while trying to find what is "broken" in it, I am told there is an update and it told me I had 13 days to do it.... Or something like that. Alas I've deleted the screen shot as I need to keep the bin less full to help me if I accidentally delete something I shouldn't.

So now I have 102.0.1

So I'm confused: What is the mechanics of rolling out updates? An update I didn't want (beside the point) but none the less broke firefox was done without my knowledge, and yet another one which was throwing up messages at me when I loaded firefox doesn't?

I don't really know what either update did.

About a week ago I started having trouble downloading large high resolution photo files. I have been downloading these files for work for over a year and they have always load very quick. I would click on the file and the entire photo file would be there instantly. However, for the past week these file do not download or download very slowly. I have checked internet speed, which is 310. I can also switch browsers and have no problem downloading the same files. So its not my computer and it not the internet, so something has changed with Firefox. Can you help?? I have used Firefox for over 20 years and don't want to change browsers, but I have to work and this downloading is a problem.

I was using Firefox and Owl (the addon).

I just upgraded to Fedora 36. I treid installing Owl and an alternative called "Dark Reader" and both cause a message stating they are corrupted.

I enabled dark mode in the browser. Google immediately changed to a dark background which I can more easily see. This site ignores the setting and is forcing me to work with very limited ivsion

I can barely make out the UI. I found what might be a solution at https://support.mozilla.org/en-US/questions/1356233 but after hours trying to read it I gave up and am wirting here.

It is very frustrating that other sites respond to firefox settings and your support site does not.

The bar that contained those items disappeared in Firefox after the update to 110 I believe. I don't know how to get it back, I've searched settings. The bookmarks and all the data appear to still be there. It's been there since, I think, version .9 something. I updated to windows 10 from windows 7 about 3 months back. I noticed the change immediately. I don't even know what the bar is called. I still have my windows 7 machine since I am still trying to resolve problem with windows 10 and I'm even thinking of going back to window 7. It did the update to 109 without a problem.

HELP!!

It is probably something simple by windows is more a game machine to me. I learned computers on a GE-645 to give you an idea of how old I am.

I'd like to import my Seamonkey profile data to Firefox, but Firefox doesn't recognize Seamonkey or its data. How can I do this? I'd like to keep my Firefox data synced to Seamonkey, and maybe synced the other way too. And I'd like Thunderbird to be able to sync to the Seamonkey email data too, for what it's worth. I thought the importing of data when Firefox starts would take care of importing SM data but it doesn't. Are there any commandline options for running Firefox that would get the importing done? I sure don't want to mess around with a huge html bookmarks file and there's other data in Seamonkey besides bookmarks that should be imported too. Help!

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

Firefox 109 is horrible and I am trying to revert to 108. I have the "Old Firefox Data" file, but have no idea how to get ALL that info back into 108. I am so very upset and frustrated right now! So much wasted time. I cannot believe Mozilla did this to us with no warning!!!!!!!! I have seen some articles on how to get the info back, but I don't really understand them. I am relatively computer-savvy, but I definitely do not understand how all this works. Some "Firefox for Dummies" at this point would be greatly appreciated. I am on a PC using Windows 10 professional 64-bit with automatic updates so it's current.

Since Firefox is set as my default browser I would have expected to see Firefox here in these registry entries as my default browser in lieu of Internet Explorer. However, if I delete those Registry entries, it then breaks any embedded links in MS Programs such as Outlook mail and Excel. I have I.E as non-active (i.e. unchecked in Programs) but the system still seems to rely on I.E for opening any embedded links. Any suggestions as to how to fix this problem would be appreciated.

Hello, I am still using windows 8.1 64bit & refuse windows 10, due to high risk privacy, yes predictable hollow words are said, BUT is Microsoft, a greedy un-scrupled money making, money hungry corporate entity, wants us to willing give it our private details voluntarily or under thin layer of extortion.

Hence my sticking to windows 8.1 as I have certain control, mainly updates.

Will Mozilla browsers be specifically supporting older operating systems like windows 8.1 into the coming years, not just months, e.g. until January 2023

Yes is a blunt question, but is eluded against in other responses, maybe is Microsoft buy out to sacrifice mozilla loyal users or similar, same query is for Brave browser. Mozilla I think is last Bastian for decency & morality, a leader in justice & honour.

I did a full reinstall of my Firefox browser because of a problem where it couldn't load some youtube diy videos (that did load in another browser). Before the reinstall I made bookmark and saved logins backups. No problems with backup/restore of bookmarks.

Exporting saved logins works perfectly and I get a readable csv file , but importing simply doesn't work. First of all the import feature was disabled by default (?). After making the change in the settings and restarting Firefox I see the 'import from file' option in the password manager.Big dissapointment however when you click the 'import from file' option and select the exported csv file because nothing happens ! No error, no result,nothing ! I tried several csv files from earlier backups but none work. Google on the other hand can import all of my csv's without any problem ! Any help on that would be greatly appreciated.

Deleting and reinstalling firefox seemed to fix the problem, but it returned after sometime; even when I just used youtube on firefox(I've tried this atleast 3 different times now). I am not sure if this is caused by one of my extensions, or if there is something else I've done to cause this. I'd just like to know if there is a way to fix it?

Hi,

To get myself off MS Edge (as its Chromium based), I've come back to FF. But after I tried installing firefox standard and even the Extended Support Release I can not run it for the first time - I get this error

Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I've followed the advice in the help pages, but it hasnt fixed the issue

https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

The same happens when I run

firefox -p

The firefox App Data folder contains no profile file at all....

I've tried uininstalling and wiping all files, and I wanted to try an old versions BUT the link on the page is dead
