What causes Firefox to do a refresh. I stepped away from my PC for 15 minutes and found FIrefox doing a refresh when I returned. Lost all of settings. Putting the icons on tool bar where you want them is one of the frustrating things I have done in a long time and now, I get to make all my settings changes over again plus try to get the tool bar icons where I want them.

After the recent Firefox upgrade a couple of days ago, I am unable to get to my Questrade login page. I click login, I get a white page with a message in bottom left hand corner "transferring data from login.questrade.com..." and no further response. I am able to login with MS Edge, and Firefox is able to access all my other websites except this one.

I have run through all the things to try in the Firefox support article "Firefox can't load websites but other browsers can" to no effect.

• cleared cookies & cache
• cleared recent history
• turned off DNS over HTTPS
• Disable IPv6- changed to true
• changed Proxy settings to No Proxy

I've turned off Bitdefender firewall and antivirus apps to no effect and ran a full system scan with Bitdefender. I really don't want to have to use a different browser each time I want to access questrade site. I would really appreciate any advice as to what else I could try to resolve this issue. Thanks so much!

There is no simple way to add mailto:"mail.proton.me in settings.

I can delete Google but there's no option add an alternative. Settings is looking for an app, not an email provider address. I had to modify handlers.json to make it work.

Currently I am trying to use the firefox built in VPN option. When I hit the turn on it turns on and goes green but I am unable to browse. I suspect this is due to the corporate firewall and content filters that are in place when I am in the office. The firewall team is looking for support as we are unable to find out what access is needed to be open for this service to work. What IP's does the service connect to for access? What ports are use for setting up that browser level VPN? Is their any application or urls that should be allowed? If documentation for what access is needed to be opened on a corporate firewall would be appreciated. We have searched extensively and cannot find the information other than this runs by Fastly. We cannot find ports/urls/ips that are needed.

Thanks Chris.

The top row in Firefox browser doesn't have any tabs, it looks as pictured in screenshot (Chrome below for comparison). I only see the icon and text for a page, but that isn't enough to know clickable area, and it makes it unintuitive.

I tried several browser themes but none of them changes this. There doesn't seem to be a setting for hardware acceleration anymore that used to solve it for some users in the past based on a search on topic.

Maybe this really is how it's meant to look but the design just went backwards from what we want to see; tabs are no longer tabs but something vague. Can never please everyone i suppose, but i want old back.

Hello, I used to have the VPN button but now I don't. I'm on Firefox v158.0 in the USA, on my personal laptop (so no enterprise policies to interfere). Here's what I've tried:

• Customize toolbar: no, the icon isn't in there either
• Start Firefox in Troubleshooting Mode
• Refresh Firefox
• Ensure "Allow Firefox to improve features, performance, and stability between updates" is on
• Sign out and back in to my Mozilla/Firefox account

I miss this feature already because it makes me feel better about using public wifi. What else can I try?

Thanks!

For some reason, the time on my browser (time displayed on Discord and such), is one hour behind the actual time. I never had Resist Fingerprinting enabled and there's no setting anywhere to change it manually.

still have a old version of Firefox on my desktop

Tried to uninstall but got message: can't because helper.exe is not in appdata/local/uninstall

found a helper.exe and uninstall map, put it in Mozilla Firefox in local. Now I don't get the message that it can't be found but app is still not uninstalled from programm files.

If I tried to apply hlper.exe by hand, it doen not work.

How do I get rid of this version 135

I always use C Cleaner to clear unneeded my unneeded data once a month. It does not usually affect my Firefox shortcuts on the Firefox homepage. It was also after Firefox had updated to version 158.0 . I did this on Wednesday (14th October) and all of my pinned Firefox shortcuts have gone missing. They have not come back, and no other shortcuts are being shown after I have since visited any websites. What has happened to them? Will this be corrected? Regards John

Bonjour, J'utilise le thème sombre avec Windows 11 depuis longtemps. Lorsque j'ai activé les thèmes contrastés (Aquatique, Crépuscule, Ciel nocturne et Desert ) avec Windows 11 26H2, Firefox 158 s'est retrouvé avec ma page d’accueil personnalisée désactivée. J'ai essayer de la reparamétrée mais impossible : la page reste juste avec le nom Firefox et le champ de recherche sans le bouton de personaliser. J'ai l’extension "Dark Reader" qui s'est aussi désactivé. Tout est revenu à la normale après désactivation des thèmes contrastés. Cordialement.

Each time I power up my laptop I want my page to go straight to my Yahoo Mail. It does do that but it also tries to open another page that errors out. I think its because there's a 'c in the address and the file can't be found. I don't know how that filename got written into the Start Up Program and I can't find it to remove it. Please tell me like a First Grader how to remove this error message.

http://"c/Program%20Files/Mozilla%20Firefox/firefox.exe%22%20-new-window%20https://mail.yahoo.com/

It says it cannot open the page.

Thank you for any help you can offer.

[redacted email from public]

I have been trying for 2 days to change my account default email address. The system gets as far as me typing in the password sent to my current default email address. I then click on the submit button and nothing happens! This has happened 8 times now. After using Firefox as my browser for +-15years, I am very disappointed by the lack of access to a human voice. If I do not hear back from you I will change to Microsoft Edge as my browser.

I've been using firefox for a little while- maybe three months now. I'm no expert on any of the config options. I run firefox using the built in VPN that my friend showed me how to enable, and I've been using it since. But now, as of roughly today, whenever I enable the VPN, no websites will load. At all. When I turn it off, they load instantly. But whenever I turn it on, it just gets stuck loading forever and ever, never actually getting anywhere. I tried enabling network.dns.disableIPv6 in the config page, because that's what I saw on a mozilla support page- nothing. Didn't do anything. The browser.ipprotection.enabled is still on, and I didn't change anything in settings. There was a firefox update very recently, but everything still worked with the VPN on. I just updated my computer, but I don't think that's it either because it wasn't loading things earlier today either. Not sure how to fix this. Please help?

Firefox update and a pop up deleted my open tabs so that I couldn't easily restore history. I tried some of the suggested work arounds but was not allowed to copy (or open file) from profile folder, sessionsstorefile. What is needed for the required "permissions"?
