Firefox 145.0, (64 bit), ASUS laptop, Windows 11, <object>PDF. Embedded PDFs do not display in-page. Issue seems to only exist on this particular device. On same ISP pages display properly on other (HP) laptop and Tablet. I've disabled a few extensions and it displays properly.

My question: Which extension(s) will cause the issue?

After the most recent update, the Home Page does not show the minimize, maximize, and close buttons, when I first open the Firefox Browser. I can click task bar / show desktop and then maximize the Firefox Browser. Once I do that, the forementioned Home Page buttons appear. It seems that a fix is needed for this glitch.

Hello Firefox community, I use Firefox Desktop on two devices — one for work and one for personal use. I’d like to have different bookmark toolbars on each device, but they keep syncing and becoming identical. Is there a way to prevent this (without turning off Sync entirely)? Or is it simply not possible to use more than one Firefox Desktop setup with different bookmark toolbars under the same account? Many thanks! Eva

A week ago I got a BSOD that ruined settings of most of my extensions and most likely some of Firefox's settings too (at least it erased my custom findbar.matchdiacritics value, but probably not just that). After that I moved Firefox's folder and re-installed it. I also created a new profile. The 2 profiles are synced. Because of that, the new profile got (almost) all the extensions from the old one automatically. Then, I decided to do a clean install of those extensions (the reason why is a story for another ticket). So, while both profiles were opened, I removed one extension in the new profile, waited for a bit and checked the old one to see if it got removed from there too. At first it wasn't, so I thought they are not synced (anymore). Yeah, sure, but once I removed all extensions from the new one, the old one woke up and removed all extensions from there too. Great! Awesome! Loved it wholeheartedly! It really had to wait until I removed them all, didn't it? Anyway, I had a backup of my old profile, so I restored my extensions and their settings on both profiles eventually. So now I have clean installs of Firefox and extensions. Back to the issue. I can't load Steam pages (at least store.steampowered and steamcommunity) normally anymore. They load forever, and if the blue dot eventually stops moving (after an insane amount of time), it's either a plain white screen, or badly loaded page with most images missing.

• Edge loads them just fine
• Steam client loads them just fine.
• If I turn on VPN plugin (I use Browsec), then it works. It's like that in both old and new profile. That's why I mentioned that funny little story before.
• Tried Troubleshoot Mode, didn't help.
• Tried to selectively disable some extensions, same.
• Obviously tried to remove cookies, Ctrl + F5 and whatnot. Btw, if I clean everything and try to load it, then it's (most likely?) a white page, but if I turn the VPN on and load it first, and then turn it off and reload it, then it will look a bit better, but still will load forever with some media missing. (Which kinda make sense since something was already cached.)
• Tried to change proxy settings from “Use system proxy settings” to “No proxy” and “Auto-detect proxy settings for this network”, nah-ah.
• Tried to disable DNS in Firefox's settings, no siree.
• The console throws different warning and errors every time (that are probably even unrelated). Or none at all.
• Probably tried something I already forgot about.

Also, it seems the culprit is actually Akamai (it's where the Steam stores its media) or whatever is preventing reaching it. Because it often shows something like “Waiting for community.akamai.steamstatic.com...” in the status bar for a long time. It seems like the problem is within Firefox's settings, and it also looks like settings aren't synced across profiles (or at least some aren't, I definitely had to configure them on the new profile manually). Anyway, I am out of ideas and my butthurt thrust is about to deliver me to Uranus. Thanks for your attention!

Is there a way to completely opt out of having AI in my browser?

I find recent implementations of AI in Firefox quite frankly disgusting. I don't want to see it, I don't want to use it, I don't want it suggested to me. Not only it's unneeded, but also all your LLMs are a waste of electricity, fresh water and are a threat to my privacy, and we don't even mention all the legal trouble AI scraping creates.

I need a switch to completely remove any mention of LLMs/AIs in my Firefox browser unless I search for it on the internet (and, trust me, I wont; I'd prefer to continue thinking for myself and having real people with skills and talents do things if I can't do them myself) and have none of them touch me in any way. Kill that thing with fire.

Ideally Firefox, one that advertises itself as a secure browser with respect towards its users, shouldn't have any mention of AI in the first place, you know. But since companies are in a craze about it for some unknown reason (trust me, we don't want it; if I want to be lied to, I'd go to a paediatrician to talk about my symptoms, not a language model I can't trust with my data), at least give your users an option to get that awful thing out of their browser it they want to.

Have a nice day. <3

With Firefox 144, there is unasked for/unwanted AI introduced. How do I ensure that all AI is completely disabled in my browser? I found a link describing some settings, but want to confirm this will disable ALL AI in the browser. I don't want it, don't trust the privacy/security holes yet to be found and would prefer it was not included in Firefox to begin with. The list I've found is:

• user_pref("browser.ml.chat.enabled", false);
• user_pref("browser.ml.chat.menu", false);
• user_pref("browser.ml.chat.page", false);
• user_pref("browser.ml.chat.shortcuts", false);
• user_pref("browser.ml.chat.sidebar", false);
• user_pref("browser.ml.enable", false);
• user_pref("browser.ml.linkPreview.enabled", false);
• user_pref("browser.ml.linkPreview.optin", false);
• user_pref("browser.ml.modelHubRootUrl", "");

Will this do it? What about:

browser.ml.chat.nimbus

Do I need to clear that field to ensure I don't get some auto opt-in in the future as more and more of this "stuff" is put into the browser?

Why not leave Firefox as a security/privacy conscious browser and put out a separate AI browser (FirefoxML?) for those that are not as concerned. How does Mozilla ensure that no information is leaked through AI from sessions for professionals that must protect physician/patient, attorney/client information or other legally confidential information?

Is there a way for me to opt out of any new "AI" functionality/features that would otherwise be enabled by default? Like the tab suggestions and perplexity in search. Having AI shoved down my throat from every corner of the internet is kind of frustrating.

Witam , Zakupiłem nowy komputer , zalogowałem się na swoje konto Firefox . Zrobiłem synchronizację , ale żadne dane się nie pobierają , ani zachowane zakładki oraz zapisane hasła. Chciałbym odzyskać te dane. Chodzi mi o dane z 14.11.2025 Dziękuje i pozdrawiam

When I try to "sign into" Firefox using Google Chrome, I see the following message: "This account is not active. Please contact an administrator if you believe this is an error." I do not know how to contact an administrator. I do not see this statement when I sign into Firefox using my Firefox browser. Maybe (I think) the issue is that I need to use my Firefox browser to "sign into" Firefox (and, not Google Chrome). Thank you for your comments about this.

This concerns the display of bookmarksto the the left of the main display. Fot the record, this is installed om Magea Linux, vers 9, from the OS repository, and is Firefox vers 140.4.0esr ( 64-bit). Up until recently the display was variable in width, and once the box for 'show bookarks' was ticked, the bookmarks display opened in any new ;Firefox' brought up. With the two new features, I have a pair of niggles. One, is that the new sidebar, being fixed width, cannot be reduced. Taking up more screen 'Real Estate', that I consider would be better utilised for the main panel. The other niggle, is that ticking 'Show bookmarks' is not permanent and has to be re-ticked, for any new Firefox' display. I have another machine running the same version of Mageia. I opened this today, and it, while still showing the same version of Firefox, displays the old version. Perhaps, since the Mageia support section have not yet.sent a prompt for update. My query, is. Is it possible for me to return to the old style display, or is there a setting that will do so. The new display, having several options, is possibly an advance. But, for me, bookmarks display is paramount.

Thanks, Rod Goslin

After the 145.0 update when I start Firefox both the menu bar and the top bar with the exit icon are missing. This is the first issue I've had since using Firefox when the new revision was in the 20's. Per some quick Support research, I press F 11 twice (NOT once) to restore the screen to include the top bar with exit icon and menu bar with my Windows task bar showing (as normal for the past 2 decades). When I close out Firefox in less than full screen mode and then start up Firefox again, it properly includes both the top bar with exit icon and the menu bar. HOWEVER, if I close Firefox in full screen and then restart, I am missing the top icon bar and menu bar... again. Press F11 twice and the bars are back to square one. HOW DO I FIX THIS SO I DON'T HAVE TO PRESS F11 TWICE ON EVERY STARTUP TO RESTORE MY SCREEN?????? WHY DID YOUR RECENT UPDATE CHANGE MY SCREEN SETTINGS?????

Does Firefox provide firewall and/or security programs for my computer running on Windows 7? I cannot buy a new computer and want to make sure I am protected - my updates are up to date and I have had faith in Firefox. Otherwise, can I use an ADD-on to do the job? Please advise. thank you very much

I have been unable to sign into my bank account online (on this computer) . Been prompted to update my browser (Chrome, Safari, Forefox, Microsoft Edge), I checked my Firefox version, says up to date. Still unable to access. Spent hours frustrated. Please help. thank you so much
