Firefox Community Forum

I made a change somewhere that caused a total loss of history/open tabs even in my tab manager extension. I can't remember exactly what it was I changed but nothing I have searched here has been helpful in recovering from this. I did not want to bring my profile from home as I am using Firefox here in a work environment. Can someone point me to or explain a step by step method to be able to do this? Nothing I found in searching here has been positive.

I’ve been having some connection issues while using Mozilla VPN with Firefox. Some websites either load very slowly or occasionally fail to open until I disconnect the VPN.

I’m trying to understand whether this is more likely to be related to Firefox, the VPN connection itself, or the server being used.

I’ve also been looking at other VPN options such as CometVPN and was wondering whether changing providers could realistically make a difference in this kind of situation, or whether I should first be checking Firefox/network settings.

Are there any specific DNS, proxy or Firefox settings that are worth checking when troubleshooting this type of VPN connection problem?

Lately, whenever I click into a youtube video from within youtube, instead of Firefox blocking autoplay, it mutes the video but lets it play.

Initially, it was muting EVERY video I pulled up, but messing with my settings has fixed the problem if I click into a youtube video from elsewhere (ex. a google search result), or if I refresh the page. It's super annoying to having navigating youtube be this non-functional right now, though, since everything just silently plays until I catch and unmute it! Any help would be super appreciated!

(I'll attach an image with my current autoplay settings.)

Setting up a new Macbook air m5 and trying to sync my profile/bookmarks/etc. on FireFox but the confirmation code is not arriving at my gmail. Checked spam and added "accounts@firefox.com" to my contacts but still not arriving. Help?

I just had to reinstall firefox today, and now my bookmarks sidebar is on the right of the browser window. I want it back on the left side where it belongs, but I can't find any instructions on how to do that. I really don't like this. Am I going to need to just switch browsers altogether, or can I get my old firefox setup back?

I have started receiving a secure connection failed error message for a portal log-in website that worked fine for the past 6-7 months (see attached document). Other people in my group use Firefox and Bitdefender to access the portal and none of them are having this issue.

I originally believed the problem to be my anti-virus (Bitdefender) and worked with them to resolve the problems. After trying various solutions including clearing my cache, using private mode and turning off different components of their software, Bitdefender believes the problem is with my browser setting and not their software. I also tried accessing the portal using Chrome in both regular and incognito modes and cannot access the site which would seem to rule out the problem being a Firefox browser problem but contacting Firefox support seems to be the next logical step.

I have been to the Firefox FAQ and saw similar problems with potential solutions - DNS over HTTPS, TLSKEYLOGGING issues, add-on exceptions - none of which worked. I have the most recent version of Firefox and am running Windows 11 home version.

Sometimes if I hit refresh after receiving the error message, the browser will try to connect and I will get a server time out message. If I keep hitting "try again", sometimes the portal log-in screen will appear and allow me to log-in. The key word is "sometimes" since often I just keep getting the server time out message.

Any ideas for me to try from this forum?

I've noticed that Mozilla products (firefox, thunderbird etc) all phone home all the time, which is a violation of both my security as well as privacy policy. In the firewall one can observe persistent, periodic, repeated connections to various non-sanctioned sites and services, apparently run by Mozilla. These include, but are not limited to:

• .mozgcp.net
• .services.mozilla.net

firefox-portal-detection.com etc.

Specifically, there are persistent, periodic and repeated connection attempts to (just copy/pasting from the first page of firewall report; there are many more as well as similar connection attempts from thunderbird as well): firefox-settings-attachments.cdn.mozilla.net:443 assets-prod.sumo.prod.webservices.mozgcp.net:443 content-signature-2.cdn.mozilla.net:443 push.services.mozilla.com:443 etc

These begin at the startup of the browser/mua and continue throughout the session. Given that none of the sites actually browsed have anything to do with mozilla per se, and given that various privacy-violating features such as DNS-over-HTTPS (yes, that's a not a privacy-enhancing feature but the opposite - it just shifts the surveillance point from the ISP to the DoH provider) and other similar "features" are disabled in-browser, there should be no user/browser connections attempted to mozilla servers.

Also, by setting up a local security MITM proxy in order to observe and analyze the content sent to and received from these services and configuring the browser to connect via the proxy, the browser seems to *stop* trying to connect to these services, which indicates *active* measures by the browser/mua to avoid it's browser-fingerprinting and location-revealing content from being intercepted and analyzed.

This is especially concerning as Mozilla actively brands and markets it's products as privacy-respecting, as for-user-rights and as away-from-big-tech-dominated. Consequently I perceive this as complete breach of trust. Even by just *attempting* such phone-home connections a leak of metadata occurs, identifying the IP, the browser and consequently the user and user's location, sometimes actively (such as was the case with now apparently discontinued location.services.mozilla.net). Combined with whatever content these connections carry, this constitutes a serious breach. And there seems to be no way for the user to configure the browser to stop making these connections, other than by using an external application firewall.

And to top it off, with Firefox version 155.0.1, the browser now outright refuses to connect to *any* sites at all if firefox.settings.services.mozilla.com:443, firefox-settings-attachments.cdn.mozilla.net:443, firefox-portal-detection.com:80 and content-signature-2.cdn.mozilla.net:443 are *externally* blocked, at least on that profile (which worked just fine prior to upgrade to 155.0.1), showing a spinner and waiting indefinitely (not even timing out). These are the *only* connections it even attempts, completely ignoring the actual site that it was told to connect to. So that's at least 4 privacy-violating, security-policy-violating phoning-home connection attempts and a complete disregard for user's actual, sanctioned connection request.

I see this in abrt:

Is this normal behavior for Firerfox 155.0 on Fedora 44 KDE-Plasma 6.7?

Any time I try to load a webpage on Firefox, I get the error which states "Firefox can’t connect to the server". This occurs when the DNS over HTTPS setting is set to 'off' or 'default'. When the DNS over HTTPS is set to 'custom', the error displayed is "Firefox can’t protect your request for this site’s address through our secure DNS provider. Here’s why: Firefox wasn’t able to connect to firefox.dns.nextdns.io." (it's the same for next DNS or cloudfare).

When I initially opened the DNS over HTTPS settings, this message was displayed: "DNS over HTTPS is not working because we encountered an error (NS_ERROR_CONNECTION_REFUSED) while trying to use the provider Cloudflare". However, this message went away and I have not been able to replicate it.

I have already tried everything suggested in the support article "Firefox can't load websites but other browsers can". I do not have any antivirus software installed. I reconfigured the proxy settings to no proxy. I changed the IPv6 settings. I changed the DNS Prefetching settings. Nothing has worked.

Safari works perferctly fine, Chrome is giving me similar errors.

I have two windows PCs, both running Firefox 154.0.1 (64-bit) on Windows 11 Pro. One PC has the Daily Crossword widget, the other doesn't? When I go into Manage Widgets, the Daily Crossword option is present on the first PC, but not the other? It's possible that I may have hidden the Daily Crossword widget on the second PC, but if so, how do I unhide it? The PC without the widget is connected directly via a LAN cable to my router, while the other PC is connected to the same router via a Google WiFi mesh.

I'm on 153.0.4 (64-bit) and after the last update, drop-down arrows are non-functional. I use Firefox at work and the dashboards that I've been using can't be used because I can't make selections. I'm having to use Microsoft Edge (yuk).

Is there something I can do to restore the drop-down behavior?

Thanks, JR

I am suddenly finding I cannot scroll a thread in Chatgpt! What changed in the last 2 days? It has been working fine for 2 years. I am on OS mojave 10.14.6 on a 2015 Model Imac.

If i want to watch a video that has geoblocker and i switch VPN on, some videos stop after a short time (2-3 min) and if i refresh the page it will again run only for a short time after choosing the scene and continue watching. Some other videos on the same page just run fine with VPN on, without any interruptions. Why is that and what to do?

Is there a way to make the desktop version of Firefox enable the VPN when ever it starts. I find it annoying to have to turn it on every single time I start firefox or open a new tab. Thanks

I cannot see imported bookmarks from previous browser after reformatting. I exported old bookmarks to a html file. It shows 'bookmarks imported successfully' but there is nothing in the bookmarks toolbar.
