Is spell-checking done locally on my computer, or is it done on the Mozilla website? I just found out that the Chrome and Edge browsers send my typed message to the home office, and that is where the spell-checking is done. Can I assume that this process is done locally on my own computer with Firefox?

I've been paranoid about security for many years, and every little bit of info I can add to my personal well-being lets me sleep that much better at night.

I am currently 82 years of age and have been using Firefox since it first became available, just because of its advertised security features. Quite happy with it and hope it stays on top of my needs.

And I have the same question regarding Thunderbird and its security properties.

Thank you.

Firefox 117.0.1 (64 bit) Build 20230912013654 Windows 10 Home - Version 22H2 OS build 19045.3448 The link to download my Sears credit card statement in pdf form has disappeared when accessing the website (https://citiretailservices.citibankonline.com) with Firefox. It still appears and works normally when the website is accessed with Chrome. I have the uBlock Origin extension installed on Firefox, but it is disabled on the Sears website. Screencaps attached.

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

I have been having this issue for such a long time now but its really getting ridiculous now, I have tried to follow so many guides and re-installs and .XPI installs and nothing is working, I am beyond stumped as to what can be the problem, someone please help me fix this.

Which file/s contains only the browser settings, not including the extensions, which are transferable to other profiles? prefs.js? the contents of the settings folder?

Everything was working fine on Firefox up until a couple weeks ago when my searches started lagging.

What happens is - if I type a search into the main URL/search bar on the browser, it loads just fine. But if I type a 2nd search into a website search bar, such as on google.com, there is about a 12 second delay between me hitting enter and the page actually starting to load. The page freezes during this time and is unable to be interacted with. This issue does not happen in any other browsers outside of Firefox.

Things I've tried so far: Troubleshoot mode/safe mode, clearing cookies and cache, uninstalling and re-installing Firefox

Nothing has helped... wondering if this was caused by an update?

I'm getting daily warning notifications from Mcafee about some virus. Don't even have Mcafee. When I go to Settings -> Privacy & Security -> Notifications, there is no Settings button to modify push notifications.

I used the support article [Hide Tab bar if there is only one tab] to hide the tab bar when there is only one tab. I now regret it and want to go back. I tried browser.tabs.tabmanager.enabled = true but that didn't work. And unfortunately I don't understand the "chosen" solution, so I can't reverse it. The regret is because it's hard to drag a single tab and drop it in another browser window.

I have Firefox installed on two PCs. I see the option to add "Recommended by Pocket" under Settings/Home, but on the other one I don't. Screen shots of both are attached. I have completely uninstalled, cleaned up all Firefox files and re-installed Firefox multiple times on the PC where I don't see the Pocket option but nothing changes. Also gone into about:config and tried making changes from there. I want the Pocket recommendations to show on the Firefox Home page for both PCs.

Thanks

So I synced my bookmarks then I notice that all of them are mixed up, so i look for ways to fix them, I then see I can restore my files, I try it then it says it was unable too, and then after that it deleted everything, I tried to restore them again and again using different dates but nothing worked.

p.s. I did post this earlier but it was in the middle of the night, so nobody saw it.

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

I am unable to login to my Prescription provider's website (which I do every day). Problem started Sunday and still persists.

I am able to login using Chrome, so I know the website is working properly.

Help - I DO NOT want to use Chrome.

117.0.1 Mozilla Firefox Snap for Ubuntu installed Total Adblock installed Enter URL "my.yahoo.com", the "My Portfolio" page comes up, the portfolio box presents a message: "Oops, something went wrong. Please try again." I went to Settings, Manage Exceptions, entered "https://my.yahoo.com" and clicked Add Exception. "https://my.yahoo.com" it appeared in the Website listing below. I clicked Save Changes. I retried the My.Yahoo tab again and the same error resulted. Where do I need to change what preferences, Yahoo or Total Adblock?

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

Past experience. With just a few tabs open there was a "+" button at the right hand end of the tab bar for a new tab. When the number of tabs got too many (in my case 18) the "+" button was JOINED by a ">" button to be able to see tabs off the right hand end of the toolbar, but still use the new tab button.

Post update to the current version of Firefox, at the point the ">" button appears it is REPLACING the "+" button.

I know there are workarounds, but my "rut" is to use the "+" to get a new tab.

Is there any way of getting it back?

I was having trouble switching and logging out of Twitter so I thought I could just clear site cookies to make it work, but I weirdly discovered "about:preferences -> Manage Data -> Remove Selected / Remove All Shown" has no effect. i.e. after clearing, when I open up manage data again, they are still there. I did not try "Clear Data" above it because I was afraid of clearing out all my logins.

I reinstalled my computer several weeks ago and current profile was directly copied from my last machine, so this might be a possible cause? Could someone be so kind to help me get remove cookies and hopefully twitter back to work? Thank you in advance.

Hello! I have used Firefox on and off so I don't have a time frame of when this would have started exactly, but I have had some random completely black screens on both of my monitors dating back to at least 2-3 weeks ago that can only be fixed by powering down the entire PC. I've reinstalled my (NVIDIA) GPU drivers, rearranged display-port cables and just about anything before finally finding a fix, switching to edge. So far I've gone a week without black screening when with Firefox I'd get around 4 give or take a week (some days getting to 3 alone). I don't know what could cause it but I have noticed it only happens when first starting a video. Mostly YouTube but other video sites seem to have also caused it occasionally, I would just like to know what could be causing this, as I do prefer Firefox vastly and would like to switch back as soon as I can.

Will provide anything else as necessary!
