Firefox won't save previous tabs IF another instance of Firefox is running including Private mode

For example, say, you have 3 opened tabs in a Firefox (FF) windows. Normally, when you close FF and then re-open FF, it restores 3 previous opened tabs.

But, if you have another FF windows opened at the same time, when you close the FF windows with the 3 opened tabs and re-open back a new FF windows, FF won't restore the 3 opened tabs.

Same thing happens when you have another Private FF windows at the same time, when you close the non-Private FF with the 3 opened tabs, and then you re-open FF, it loses the 3 opened tabs.

That's why you can see 'countless' question about lost opened session, because of the issue above along with crash etc.

Is this a bug or a known feature?

Hello, I've got a bit of an issue with Sync. So, my current sync profile is outdated by ages, and I'd like to delete it completely and update it with all of the information on my desktop browser. But, when I try to enable sync on my desktop it overwrites my desktop profile with all of the outdated information saved on Sync. I can't seem to find anywhere to delete the saved Sync data so that I can upload a new copy.

I hope someone can help, thank you!

duplicate of /questions/1466153 thread

I thought I had solved this by adding the website to the "safe" list - I really cannot say how frustrating this is if I am being locked out of even safe sites. - This is a browser issue (I'm not that naive).

There is no real response from Moacilla(Firefox) here apart from throwing the Rulebbok at me and saying "Read!". I can only do so much Tune ups" and shut downs and ensure drives are functional. Please advise on the Browser Cache situation, rspecially as BBC iPlayer is added to the "Safe List" and yet still throws up the 400 Bad Gateway error message - an early reply would be useful.

The other day I accidentally pressed a keystroke that changed a Firefox setting, and now it thinks I'm on a mobile device/displays sites in mobile view where possible by default. This has persisted despite restarts of the browser and the computer and has been happening since Sunday (Australian time). I've tried opening the Responsive Design dev tool and I've sent screenshots to a techsavvy friend (I'm totally blind and use a screen-reader, so couldn't tell this was happening until I tried to use a site that had a radically different layout in mobile view), and aside from not seeing an exit button or a switch to change device mode, he couldn't tell what was going on.

I'm stuck and need help! I would like to unmobile my Firefox!

Hello. Recently I've noticed video quality has been reduced on amazon prime video. I get a message saying my hardware doesn't meet HDCP requirements.

I've already tried playing the same video on edge, and the quality selector was fine there, full HD video.

I checked the about:config toobars and I cannot find it, or am I in the wrong place ?

I think started some time this year, I can't find a Firefox download that installs without admin rights from official website. The .exe and .msi options all require admin privileges.

1. Is there still a no-admin-rights version available? 2. If not, why was it removed? 3. Any plans to bring it back?

I installed firefox from windows app store, because it would not install from the mozilla download. I did install however it will not connect with any web address. Absolutely none, I have tried all the typical solutions and none have worked. I had firefox for many years. I had to uninstall and do a fresh install. I am on a desktop running Windows 10 Pro X64. Please Help! I hate Chrome, (it is working but, I hate it).

Firefox on my 2018 MacBook Pro started having issues downloading all file types after I disconnected Dropbox sync and backup. Each time I try to download a file, a failed message is displayed below the file name and type. The browser was using the downloads folder that was synced with Dropbox. After disconnecting Dropbox, I tried changing the downloads location, but the "Choose" button does not display a window. The result is the same whether the Always ask you where to save files is checked or not.

I have gone through the following steps trying to resolve this issue with no success.

  1. I have reset/cleared any configuration setting found using about:config and browser.download.
  2. I have launched Firefox in troubleshoot mode and tested downloads with no resolution.
  3. I have uninstalled Firefox and installed a fresh copy from mozilla.org with no resolution.
  4. I have set the downloads folder in Safari, but this did not provide a resolution. Downloads work as expected in Brave and Safari. The current downloads location is the Downloads directory on my iCloud Drive.

The second screenshot with the error attached in still referencing the Dropbox-connected Downloads folder. No other browsers are using this folder and the Dropbox app has been completely removed from my laptop.

I use Firefox for web development and need to be able to download various files throughout the day, so this has become very frustrating.

Any help is greatly appreciated.

Cheers,
