Having used Firefox for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?

Few days ago, some of our clients and few (not all) internal PC are get stucked on a PR_CONNECT_RESET_ERROR on our website. Only on 117 windows version (118 developer version and 119 nightly seems ok). We tried to repair firefox, it works on 95% but we can't ask our client to do this. It works on Chrome & Edge.

We running out of ideas : - we only accept TLS 1.2 / 1.3 - checking CSP - Both IIS and Apache are not working - Firewall are not blocking

I don't know if this is a system wide iOS issue or something specific to Firefox, but I'm not able to disable link preview when long pressing a link. I was able to disable it in Safari which also disabled it in iMessage, but link previews are still showing up in Firefox and Firefox Focus. It's very surprising for a browser focused on privacy and security. I should not have to make a connection to another server in order to see the URL behind a link. Automatically downloading from an unknown URL opens my device up to zero day exploits and privacy violations. Does anyone know how to disable this completely or submit a bug report to Firefox?

A few days ago links in messages stopped working in Outlook (Microsoft 365) on my Windows 10 Pro 64-bit PC.

Good ol' Microsoft support reset Firefox on the PC and I lost all bookmarks, history and personalized settings. Tried to copy data from Old Firefox Data file into profile on reset Firefox. Didn't work. Uninstalled and reinstalled Firefox and tried to copy data from old profile to new profile. Nada.

Only option now is to try to sync Firefox on my Mac to new install on PC. I'll still lose some bookmarks and history but it will be better than what I have now. I have a Firefox account on both devices but when I log in to Firefox on the Mac I cannot find anything pertaining to sync.

Problem one: how do I navigate to sync in Firefox for Mac. Problem two: when I bought the Mac 6 years ago I tried to sync Firefox on my PC to the new Mac. For some reason Firefox synced the empty new profile on the Mac to the old PC. I lost all bookmarks and history accumulated on the old PC! I do not want to go through that again.

I have never found anything on Mozilla that clearly explains how to control which way the sync works. Must be certain that I'm copying all the bookmarks, history, tabs etc, from the old device to the new on and not vice versa.

Hi All,

We can't see video's and posters in our website when we are opening from Firefox, We are getting below error message (Attachment ) and it is only happening from new version(115 ,116 and 117) of Firefox and old version(111.0.1 (64-bit)) it was working as expected.

Can someone help on it please , We have to update our browser to 117

We have a number of websites that are accessible with a client certificate.

We have a user where with one of the websites, Firefox point blank refuses to ask for or supply the end user's client certificate. With no client certificate, they are not allowed access.

Other websites requiring the same client certificate from this user work fine.

We suspect the end user pressed cancel on the "select your client certificate" popup, but we can't be sure.

How is it possible to completely reset the remembered state of a website, so that Firefox forgets any past interactions, and will ask to choose the client certificate again from scratch?

I want to make the bottom scroll bar specially to be appeared only on hover and not when scrolling or even make it 100% transparent? I really dont want the bottom scrollbar to interface

Since 117(Beta)I have an issue with Firefox refusing to apply the update it downloaded. I've tried searching left and right on the internet for a solution and one does work which is installing the newer version of the browser each time myself. But this is ofcourse not a solution in the long run.

It tries now to apply the update 118b9 to stable version 118 and it did downloaded just fine and asked me if I wanted to close the program to let it update which always worked. I've tried different DNS to see if that could be the problem, tried a clean default profile to see if that helped, I haven't tried uninstalling it and reinstalling it, due to me losing my passwords and what not.

I also tried to run the stable version to see if the issue was still there and it is still there, so me using the beta channel isn't the issue here.

This is a recent problem. This did not happen several months ago. I read that this is a preference but cannot find it anywhere. I use video download helper. Cannot find a preference there either. Thank you for helping.

Recently, about one out of four webpages that I try to visit seem to fail to load on FireFox. This is FF for Windows, and is the most updated version. This issue even occurred just now when typing in MOZILLA.COM. Everytime one of these pages fails I attempt it with Chrome or Brave, and it works just fine. It does not matter whether they're ventured to through Google links or other links, or whether I type the address in manually. It only happens sometimes, as other times the same page loads just fine.

Hello Mozilla Support Team,

Since one of the last updates firefox Download Setting seems not work properly...

Into Settings > Files and Applications > Downlods > Save files to option is ALWAYS on, even when "Aways ask you where to save files" option box is checked. When I open a PDF in view mode with Firefox, it automatically download it to the location described into "Save Files to"..in my case Desktop. It seems that the "Save Files to" option doesn't gray out when "Always ask..." option box is checked.

Do you have any idea why I can't chose just one of the two options?

Thanks for you help...

Alex

P.S. Attached screenshot...

How do I get back a previous session of Firefox (windows)? Firefox froze up. I restarted my computer. Now my session in Firefox doesn't show up at all in 'History'. Isn't there a way to recover a previous session?? I've never had this issue before and had a lot of important tabs in that session that would take many hours to try and find in my complete history from all links.....

I started getting screen flashes and then identifying pop up windows that go to adform dot com addresses, that are blocked on my computer so nothing other than a error shows up. Its annoying and random. I have checked security page and it says Block pop-up windows and this is blocked. Two exemptions are there which are acceptable. I have run virus checks on Bitdefender and Malwarebytes (Latest versions update) nothing is reported. - What is causing this and how do I stop it? After opening up the hidden window that flashes it tries different pages all fail then eventually the pop up window closes on its own.

Using latest version of Firefox browser 117.0.1 (64 bit) Don't get the pop ups on Google Chrome.
