Firefox Support ƒe Forum

Yesterday the option to make Firefox my main browser turned on on my Android phone. It won't let me turn it on. I have Google on my phone, but I never updated it, I updated myself yesterday, I can't turn it off. I also have a MI browser that is disabled. When Fitefox is not my main browser, I cannot add web shortcuts to the start screen, and I use it all the time and miss it a lot. What should I do to restore the option to make Firefox my main browser? I used to have Google but now I don't know what's going on? Help me please!!!

I am using https://infiniteajaxscroll.com on my website https://madway.net . When I scroll down and new set of topics loads, if it contains html5 video it will not load, stay loading. Works fine on Edge browser and Android browser.

Using latest Firefox.

As per subject. After i close FF - and it is no longer showing as an app in Task manager. When i try to restart it, it says it's still running and i have to ask it to close FF before it will open it again. AFAICS It happens randomly.

It may be relevant that when using CCleaner, it often (randomly) hangs when cleaning FF internet cache and says FF needs to be closed when it is already closed and does not appear in task manager. If i ask CCleaner to close FF, the application hangs.

Less likely perhaps to be relevant: i got a rogue change of Favicon on one site. I eventually deleted the relevant file hoping the Favicons would repopulate. Most have, but many haven't including hotmail and protonmail sites.

There seem to be many causes/solutions to FF hanging but i thought these specific circumstances might make it easier to suggest what the problem is exactly and how to fix it.

Thanks.

I run several of my Firefox windows in compact sizes, and there are just so many little icons taking up space in the address typing field (what do you call it? It isn't the address bar).

I do not use the Tracker shield. I do not use Padlock "Verified". I do not use "You have granted this website blah blah permissions". I do not use Open in Picture-in-Picture, or the bookmark buttons.

These features, when I need them, I would rather access from somewhere else, like from a menu or with a shortcut key combo.

See the image of how cramped it is with the imo superfluous buttons that for some reason decided they have to live in the text box, preventing me from seeing what I type.

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

Hi, I get the below error message when trying to login to visma.net (for work).

json.parse unexpected character at line 1 column 1 of the JSON data

On this note I have a previous error, loggin in to this site that was fixed by a support member (• accessibility.blockautorefresh = false), but I have the above hurdle left. I can get past it by clicking backspace but thought there might be a better solution - maybe some other setting I can adjust similar to the first fix I got help with.

The web address for this error message shows as: https://api.home.visma.com/home/rest/sso/login

hello. I have a reproducable issue with Firefox. If I use the touch keyboard on Firefox and then exit Firefox without without closing the touch keyboard, when I next start Firefox it only opens with a half view. if I close the touch keyboard first and then exit Firefox it opens as normal in a full screen view. it has nothing to do with either an extension or a theme. is there any way of ensuring that FF opens in full screen view if I forget to close the touch keyboard before exiting the browser? thanks in advance. PS: device is a Surface Pro 7 running Windows 11.

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

I Closed the browser and forgot that I had a private one open too. When I went to open the main Firefox window up, my previous session was wiped! I already tried the right clicking plus sign method to no avail. It just brings up the one I had after searching how to bring back the session and then accidentally closed the browser after. Any tips on how to get it back? Why does this happen just because you have a private window open??? Change that ASAP!

Lastpass extension/icon isn’t showing up in Firefox IOS. I’ve installed the latest versions of both. Firefox menu or settings doesn’t offer a plugins or extension link anymore. It seems Firefox has lost functionality in this regard. Please advise on how I can get the Lastpass extension working in the Firefox browser again.

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS and there are no Extensions for the iOS version.

HTTP/3 doesn't work regardless of my config:

network.http.http3.enable = true network.dns.httpssvc.http3_fast_fallback_timeout = 0 network.http.http3.priority = true

and https://cloudflare-quic.com/ and console still show I'm using HTTP/2. Tried on Firefox nightly and chromium (chromium works fine but firefox doesn't.)

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.

Please HELP -- I can no longer use Thunderbird or Firefox to access my emails at the University of Vermon (UVM). For over about 2 months after the Univ. of Vermont went to a new email system, I can no longer use Thunderbird or Firefox to get my emails. I get an error message when I enter my NetID and password at

Hi! I have two Firefox accounts, one for work and one for personal use. I often have them running on the same computer at once (this does cause them to crash occasionally, but not often enough to be a problem). However, today I tried to log into a website where I regularly do freelance work and received this error code: "Error code: SSL_ERROR_PROTOCOL_VERSION_ALERT"

I would assume something was wrong with the website itself, however when I went to that same site on my other account, it loaded just fine. I've restarted my computer, restarted firefox, deleted cookies and caches and browser history, but still get the same message on my work account. Any idea how to fix this?

Thanks!

I don't know when it started (quite awhile), but when I go to some websites even in FF safe mode, I wait a long time but get nothing displayed and it stops spinning/waiting (the circle arrow upper left stops). Occasionally when I reload, it comes up but usually it doesn't. Other websites it works fine.

In fact, if I browse to some websites, sit and wait awhile, then go to chrome or edge, type in the same website, the page displays even while FF is sitting there waiting.

ebay.com seems to work great, but for instance this morning, this one doesn't: https://www.crowdpac.com/news/741938 but sometimes this works: https://www.crowdpac.com then try it again (refresh) and it never responds.

And in fact, I'm using Edge to submit this question because when I browsed to https://support.mozilla.org/en-US/questions/new/desktop#search in Firefox/Safe and clicked on the Sign-In/Up button, nothing happened. With Edge it worked fine and I'm able to type this in.

I need to install Firefox on a new laptop under an existing account, but a new account was already created on the new device. All it will let me do is reinstall under the newly created account.
