Although set to open previous pages and tabs it doesn't do so, furthermore I must sign in to all e-mail accounts, google, Facebook etc every time I open my Firefox Developer Edition

Hi. I'm on Tahoe since 24 hours. I have Lulu installed. Lulu blocked an outgoing connection called ping sender that wants to connect to 34.120.208.123 and is related to Mozilla as Lulu says. But when I run a whois on this ip I get

Hi!

I am having a problem with Firefox where: - if I am searching in the address bar in one tab (tab A), - but then before that finishes loading, I switch to a different tab (tab B), - Firefox will switch me back to tab A once tab A finishes loading. It's not immediate and is a little aggravating as it pushes me out of what I was already doing.

I'm currently on Firefox Beta (145.0) on Windows 11. I've tried the "When you open a link, image or media in a new tab, switch to it immediately" setting.

On my Facebook feed/timeline images don't show when I use Firefox and they are visible when I use Microsoft edge browser. I googled and I found this explanation: The most common reason for photos not showing in your Facebook feed is that an add-on or extension you have installed in your web browser (often Firefox) is blocking the photos being loaded from Facebook.

Will someone, please, tell me the answer to my question

All searches get blocked by reCaptcha, quoted as being caused by 'unusual activity on the network' After going through the "I'm Not A Robot" process the search is o.k., but this happens for every search. The problem does not exist if I switch to Chrome. How do I fix this?

Guten Tag,

Im Firefox Developer habe ich seit ca. einer Woche das Problem, das die Lesezeichen nicht mhr funktionieren. Kann weder etwas anzeigen lassen, hinzufügen noch importieren.

Das zweite Problem habe ich heute 07.11.2025 festgestellt, habe einen neuen Tap geöffnet und es werde auf einmal die gespeicherten Webseiten nicht mehr angezeigt.

Was kann ich tun? Developer habe ich gelöscht und wider installiert, auch resettet, doch es geht nicht. Auf der zweiten Firefox Brwoser habe ich zwar die Lesezeichen, doch kann keine Webseite mehr hinzufügen. Auch bei öffnen eines neuen Taps, sind die gespeicherten Webseiten verschwunden.

Hi, I am using Firefox Developer Edition though I have had this problem with Firefox in the past. The problem is that sometimes the audio from Firefox just stops working, everything else in Windows works but not firefox, I tried having the same youtube video on Firefox and Chrome annd it worked on Chrome. There are times that a Windows restart fixes it and there are times that I just have to wait a couple of days till it fixes itself. The only thing I could find to trigger this behavior is to have mi Bluetooth earphones connected, then disconnect them and sometimes when reconnecting them the audio is just gone. This usually happens when I am working, when I start the day I put them on and start some music on Youtube, after 3-4 hours I do a 15 minutes break and during that time I charge the earphones, when I come back and turn them on again, most of the times the audio is gone. Is this a known issue or something? I can send anything if you want. Thank you

This is only an issue in the firefox browser - chrome, safari and edge are fine but the drop down text in firefox on some form drop downs is a weird unintelligible font

if i search something on firefox the search bar doesnt show english and after clicking enter for the answer sometimes it doesnt come in english. i have chosen english as the only language but sometimes i get results in bangla too. i want my results to be in english only.

Which version of Firefox (Windows, Mac & Linux) will make the local network access (LNA) enhancement generally available? We at Box would like to inform our joint enterprise users and administrators to expect this enhancement and provide them guidance on how to manage this change.

I am on Windows 10 Pro (extended to Oct 2026) and use the Firefox profile manager at startup since I have more than one profile. Today (11/12/2025) I attempted to start Firefox and the profile manager window would not populate. the window was blindingly white on my dark background. I closed and restarted umpteen times but it refused relentlessly. I was about to uninstall firefox and then decided to see if I had actually installed it on any of my mobile devices. And indeed I had it on my ancient Apple iPhone 7+. And it was synced! I refreshed the sync and indeed it picked up my most recent activity from last night. All tabs were synced. To make sure I had another synced copy I also installed it on my iPad. I synchronized this too and suddenly my desktop browser started working again.

I don't know what caused the lockup of the Profile Manager but I am afraid it might happen again. What causes this and what can I do to regain control without having to reinstall? I am a researcher and I have over 1000 tabs open.

When I open Firefox it can't find my profiles when I go into the profile manager it shows no profiles. Going to my computer I find the profiles where they should be. However under program files there is a Mozilla Firefox normal directory. Did they recently change default install areas or did something else screw up.

I have done malware scans using Malwarebytes and spybot and my antivirus program and all comes up clean. Windows is up to date, Windows 11 most current preview. I can't tell you the current Firefox version since it won't open without the profile. I did just create a new profile and Firefox version is 147.0B7. also just recently right after what I think was an update that lost all my open windows and tabs and there is no way to restore them if there is a backup anywhere

All of a sudden I cannot check out using shop on my IMAC. It has worked for me for years and now all of a sudden it stopped. Not sure what settings to edit. I can go through the check out process, but when I press check out the page will not load. I just get a shadow & spinning like it's trying to upload but it never does. If I switch to Safari I have no problems, but I prefer Firefox. Any suggestions or solutions appreciated. Lorri

Over the last five hours, I have gotten 27 emails from Firefox Monitor for this data breach, for the same email address. I have already marked the breach as resolved in Monitor but I keep getting emails. Is there anything I can do about it?

Hi. I can't access my add-ons that I installed. When I click on the extensions icon it doesn't open that little menu like it does for other people, but it takes me to 'about:addons' in a new tab. I also want to pin my addons to my toolbar which is also not working. Please help me out

I keep receiving a popup seeming to be from McAfee security regarding a virus on my computer. It isn't from that security firm. The ad locks my system till I shut off and restart my computer. This is very annoying and occurs on all installed browsers. Is there anything I can do about this annoying thing?
