Lost Firefox data after trouble shooting ""A copy of Firefox is already open. Only one copy of Firefox can be open at a time" error on Mac. Any way to recover my info?

I had an issue where when I tried to open firefox I received an error that said ""A copy of Firefox is already open. Only one copy of Firefox can be open at a time". After looking at some other support articles I came across this article that appeared to fix the issue after entering a command in terminal https://support.mozilla.org/bm/questions/1254772, and I guess I deleted the wrong version because after being able to reopen my browser I had none of my saved bookmarks, extensions, history, or any other account info.

Is there any way I can recover my lost browser info or am I just completely SOL?

Hello - Firefox Bookmarks are wonderfully intuitive and hardly need the well written instructions. However, in Manage Bookmarks, I search and find the Bookmark I want but can't see or find which folder it's in. Thus I can't sort it or move it to another folder. A column in search results showing Folder would be fabulous!

This is a problem unique to Firefox. Even a page that's been supposedly formatted for printing turns out with missing text or text overlaid on other text. And it's a problem that has been occurring over many iterations of the Firefox browser.

Here's an example that prints fine in Edge and Chrome: https://www.allrecipes.com/recipe/220867/falafels-with-yogurt-dill-sauce/?printview

What is the problem, and why can't/won't Firefox fix it?

All of a sudden I'm getting the Yahoo maiil ID changed to Google Mail with out any authorisation on my part ? I know Google owns Yahoo. I use Yahoo mail all the time and Yahoo is my ID for many applications so why has this happened ? If something like this can change unknowns to me does this mean that Google has control of my MAC and FireFox and its content .??

What is the last Firefox version that works with MAC Lion OS X 10.7.5?

I have a study program of that vintage that plugs into firefox and the version on the computer now is 3.0.10 (from year 2009 and the program does not work with it.

The program is compatible with Lion OS X 10.7.5 but the Firefox version is too old.

The version 3.0.10 on the computer does not work well with most sites or crashes. The intent is not to expect to browse, just be new enough for this program for its dedicated use.

I'm confused by this issue as Firefox worked fine until recently but an older version doesn't fix the problem. At first I only had issues with LibreOffice and Firefox. LO would only open in safe mode, Firefox opened but did not working correctly. The fix for LO was to disable skia so I suspect that is the cause of the Firefox issues, but it could also be a driver issue. Weird thing, Google Chrome also uses skia and although I had an issue with Chrome suddenly not loading, an uninstall/reinstall fixed it. I am aware skia is a Google project so it may be that Chrome and Firefox use different versions of skia.

Issues: Firefox opens and I have my extensions etc across the top but the main window is blank. No websites display. Switching tabs doesn't work. If I open a "More troubleshooting information" tab for example, I can only access/view that tab by closing the first tab. A few menu options work (help menu - Troubleshoot Mode and More troubleshooting information both work fine) but Settings doesn't work. I tried Firefox in safe mode but it makes no difference. I tried refreshing Firefox but it makes no difference. I tried clearing the startup cache but it makes no difference.

This is on a dual boot with Windows 10 and Ubuntu Studio 21.04. I also have Firefox v93.0 (64-bit) installed on the Linux partition and it works fine.

I've been trying all day to get to Amazon. No go. I've checked here, and found old threads about this problem. I've tried what was suggested in them, but still not able to open Amazon. There was another site that I could not open, also, with the same error message, but I cannot now recall what that site was.

Please help! I need to check on an order from Amazon that I placed just yesterday.

Now, in the old Firefox, you used to be able to select "Email Link" to send a URL to someone by e-mail in your favorite e-mail client. I used to do that routinely, sending links via Thunderbird. I'm now using FF93.0, and all I see is "Share", which, when you point it to "Mail" it dumps you in Chrome. Now, in my FF prefs, I have specified Content Type->mailto->Use Thunderbird, so why it's dumping me in Chrome makes no sense.

How do I use Firefox to share a URL in Thunderbird like I used to be able to do?

I have this problem since version 92.0. I've been through all of the troubleshooting steps and they made no difference. I'm on a Mac and Safari works fine. When I open pages, it's usually using "Open link in a new tab". most of the time, the new tab is blank with the address at the top. If I click the refresh button, I get the page I was linking to. I have not seen the problem when I use "Open link in a new window".

I truly hope the developers at least refer to this site for concern requests for fixes.

It seems every about:config fix for the spacing of the bookmarks as well as the photon/proton fixes are doing nothing on Firefox version 91.

Is there anyway to get a simple checkbox that fixes the views for desktop? The whole world is not working on tablets or phones and this is so frustrating to see functionality continually broken with updates that are obviously required because of security issues that plague the online world.

Can any developers please respond to when users can see a fix to this issue? I know this is far from life ending but it breaks the visual aspect of the browser so badly.

Since updating to Firefox 93.0, I notice that downloads from certain sites are being blocked, because they are using a basic HTTP connection, requiring me to explicitly allow each download. I understand that this is a new "feature," as explained here: https://blog.mozilla.org/security/2021/10/05/firefox-93-protects-against-insecure-downloads/, however, I in no way desire this behavior. It is an asinine nuisance, and if I cannot disable it, I will have no choice but to revert to an early version of Firefox. My question, then is this: is it possible to disable this check, and simply allow all downloads? If so, how can I do that?

After installing FF ver. 91 for Mac OS (desktop) GMail will no longer load its themes, and only appears as a black and white simple HTML version. Many of the page functions are there, but invisible, and can only be found by hovering the cursor over the general area where these active and regularly used GMail features are on the page. Many page elements also have wire frames around them. Even the GMail log in portal screen is not displaying correctly. The Google Workspace logo also fails to fully animate when navigating to the login page.

Reverting to older versions, FF 89 and 90 proves that the problem is with FF 91. The issue does not affect Safari or Chrome in my experience. Totally clearing all cache, cookies, sync'ed profiles and user accounts in this FF product does not fix this issue with FF 91.

This appears to be an interface bug that needs to be sorted. Can you please help?

hi,

Maybe someone had the same problem, I use two security option outside of Firefox: 1. /etc/hosts file, all the site that I do not want to allow my machine to interact with; source: https://github.com/StevenBlack/ 2. VPNs anti tracking scripts

I use a mac, Mac OS 11.6 Firefox 93.0


With all the two security option enabled, Safari works fine, TOR works fine, Firefox has massive issues with loading pages speed. Some of the Firefox settings: Network Settings: the DNS over HTTPS is OFF, as I am using a VPN Privacy and Security: set to standard, but there is no difference is loading speed when switching to strict Extensions: I use 1password, multi account containers and user agent switcher; no difference is loading speed if I disable or remove all extensions

Any idea why is Firefox loading page speed effected?

Many Thanks Michael
