Firefox Support Forum

I got corrupted twice last year looking for help. Listed web pgs were scam. Someone with firefox advise me the best ad blocker, MY computer runs several minutes . Ad blockers and pop ups are so enoying

Hi,

Where does Mozilla Firefox saves the files from add-ons? Don't know if it is from Windows update or from Firefox update, but my add-ons settings keeps on resetting and I lose a lot of data from them because of that. And if I know where Firefox saves those files, then I can make a backup for them.

I'm getting this odd error with the standard install of FF since the last few updates every time I try to load FF (even starting up with a blank page) or open a new tab. Tried a fresh profile .. same result. Completely uninstalled FF & deleted the existing profile, then installed again ... ditto. Ran in FF safe mode .. ditto. Disabled hardware acceleration .. ditto. Scanned for nasties (ESET) .. nothing. Installed the latest portable version .. worked fine. Copied the old profile into the portable version .. worked fine. So what could be causing the installed version to give the 'Gah ..' error, both on starting up FF & opening a new tab, but not affect the same FF portable (same version)? The system is an ASUS laptop Win7Pro 32-bit. It's my wife's pc and she uses IE (gasp), so it's not a life or death situation. I'll use FF portable & update now & then unless there's a fix??? One final observation - the first time FF is run after an update or a fresh install, it oddly works then, but shut FF down & restart it .. and all I get is "Gah.." - Gah indeed!

For the past week or so I have been unable to play any Netflix videos in Firefox. Netflix works fine in other browsers and all other video streaming sites I've tried in Firefox still work. Initially the problem was that I would just get stuck on the red loading circle, however, after updating Firefox to the latest version (version 53), I now get an error message on Netflix telling me to check I have the latest version of Firefox, with an error code, F7702-1003. A solution posted from about a year ago involving changing the path in profiles.ini did not help, nor did removing pluginreg.dat.

I would be grateful for any assistance.

Never had problem with downloading files via Firefox from Google Drive until now...instead of file download I get tab page with following url: https://doc-04-c8-docs.googleusercontent.com/docs/securesc/jom0u67oa0tfigrh4n9sea600sv1527e/s7srbc6ckut7m2fm1eeurtos8v4ecb70/1493064000000/07580902641423571478/07580902641423571478/0B1FDjJYZYLbhRTlLQmtERjVCZ2s?e=download&nonce=4ekqosb5geo8u&user=09357804788864382250&hash=t8fpbl8um4ju2acaskk56nd6e491l86b

Uploading to GD using Firefox works..MS Edge and Chrome download fine...reinstalled and refreshed Firefox..tried troubleshooting tips for download problems per Mozilla help page and community forum..no MIMEtypes folder exists in my profile folder..any suggestions?

I cannot access a clients site that I'm working on due to an HSTS error, I used to be able to bypass this with test.currentTimeOffsetSeconds, however it seems to not work anymore.

I use Firefox for development because it has better tools than any browser I've use in the past, however this is a real blocker for me, since the sites I'm working on don't have DNS names yet and can't get updated certificates till then.

I've also manually added an exception in the certificate options, though that also didn't work.

Please guys, I've always been pushing people to use Firefox, though if it starts limiting my options without any way to bypass it if I feel I need to do something, then I'll be forced to go hunting for a browser that gives me more freedom, not to mention this is costing me work hours.

I use google as startpage. I only use Google and potentially wiki as search engines, yahoo is not even to be found in the list. I have no addons or what ever that I know of that use Yahoo, neither have I installed anything that uses it.

Yet since a few days Yahoo has replaced my standard search engine (google) whenever I type in a search in the top-right textbox.

I've checked all settings and nothing has changed. Google is my standard searchengine still. In the list with search engines, there is no yahoo to be found.

So how the f... is yahoo being used as the search engine when I type something in?

It's even worse. This morning I was behind the PC and performed some google searches. I leave the PC for a few hours, come back and do a search... and suddenly Yahoo is my search engine without me having changed anything in the meantime? WTF?

What is causing it and how can I get rid of the disgusting Yahoo search that I absolutely hate?

Hi,

I need a support from the technical team of Mozilla Firefox as I am unable to open the email website of Microsoft. I am entering the website address as www.hotmail.com or www.live.com into the search engine and I am getting the error as the secure connection failed.

May I know the reason why I am getting this error on your browser?

Even I tried many times and getting the same issue.

The website is not restricted as I better understand. It is the website which when I am opening to the another browser it is fine.

Please reply me as soon as possible as I am only using the Mozilla Firefox as the browser for my surfing and emailing.

Thanks, Tushant Rajpal

This problem is weirdly specific, I have tried other browsers and firefox is the only thing affected, so its firefox specific. When I first open firefox, firefox itself opens and loads within seconds perfectly fine, I can do things with it offline perfectly fine (like using it to open a file) But when I try to go to any website, it takes ages to load and function normally. It doesnt even matter how many tabs I open, I can load one website, or three, it takes the same amount of time.

Once it has loaded the website(s) it functions completely normally! I can load new websites or pages just fine, and everything works perfectly, until I close firefox and open it again. Its driving me insane because I'm not going to just leave firefox open at all times (This is a gaming PC, I try to not have too many unnecessary programs running in the background)

I have tried several things, I reset firefox, didnt work. I have reset my PC, didnt work. I ran firefox in safe mode...worked! So it must be a add-on or extension, right? ...Nope, turned them all off one by one and every time it didn't work. (I only run uBlock anyway)

So whatever the issue is, has something to do with something safe-mode would prevent/turn off, but not add-on's/extensions.

EDIT: Forgot to also mention, I tried clearing cache/cookies/history as well, so pretty much everything short of a completely clean re-install of firefox with none of my personal data, but hoping to avoid the nuclear option if I can.

This morning I started getting this error on the gmail site this morning. GMail is working fine in Chrome and in the app on my phone so I'm thinking this is a Firefox issue not a GMail one.

I'm only able to test on one computer right now.

Firefox 53.0.3 on Windows7 I'm also using GMail Notifier 0.7.4

An error occurred during a connection to mail.google.com. Peer received a valid certificate, but access was denied. Error code: SSL_ERROR_ACCESS_DENIED_ALERT

Ok, First my problem as the question goes... I have tried to right click on anything of firefox, websites, firefox_menus, nothing works. I can't use the right click button at all.

Now lets get some info out of the way:

1) My mouse is regular, it's fine, it works on other browsers like internet explorer, it works on my computer, allowing me to right click there all I want. But I can't right click on firefox or any website on firefox.

2) I have already tried the safemode for Firefox disabling all apps. Didn't fix it.

3) I have already uninstalled firefox completely including appdata and Install it again. Still have the same problem.

4) Tried starting my pc in safe mode, that also didn't help at all.

When did all this started? When I installed the latest firefox 53.0 (32bit)

I am using windows 7

Please help me, this is starting to make me sad and I need the right click for homeworks and saving pictures from the internet among other needs that come with the rightclick.

I have Windows 10 ,firefox 64bit 53.0.2 when displaying my hotmail. In the background (on top) it displays a banner that says "web page is slow,,," The banner is only partially readable and jerks so that I cannot read/write on my hotmail page. I need to turn off the banner. help

Hello,

After the last updates of firefox and flash, I cannot play any flash game - all of them works very slow. I tried everything, described in the forums, without success (disabling hardware acceleration, reinstalling, etc.). Everything works FINE in Opera, Edge and Chrome. Just in FF is very slow.

I use: Windows 10 (64 bit) Firefox 64 bit (latest version) Flash player (latest version)

Thanks in advance for your help!

Best regards!

Ok, Ive been having this really annoying problem. Been having it for a little while now. Ive noticed only on youtube that 1080p video's play back is choppy. The videos will freeze and then start playing after a few seconds, audio keeps playing. I started doing some testing. Ive found out that its only 1080p videos at 60 fps. If its not 60 fps it will play the video fine. Ive tried downloading google chrome to see if it did the same thing. Google chrome plays 1080p videos at 60 fps fine. So that rules out it being the computer I think. Video's off line play fine also, I tried to uninstall firefox and reinstall it didnt fix it. Only add on I have on fire fox is adblock plus. This issue is starting to drive me nuts!!! Not sure what else to do.

Yesterday, I have no idea how it happened but I was in the middle of working when the ability to open a new tab vanished... no more + sign available to click. Appreciate your help!

I installed the latest version of Firefox on my new Windows 10 laptop. Some sites including google.com and some Mozilla pages are giving me "your connection is not secure" errors. I do not get those errors on the laptop with IE or Edge, and I do not get the errors on my Windows 7 desktop PC running an earlier version of Firefox. I had FF set to be the default browser on the new laptop so out of frustration I uninstalled FF. What could be causing these messages on reputable websites?

Having a problem with cursor freezing so went to task manager and discovered 3 Firefox (32 bit) running. Rebooted. When I opened Firefox. there are three apps of Firefox running, 1 as an app, 2 as background processes. Ended one Backgrouund - no reaction. Ended 2nd background and lost this tab. Is there 1 per window? Used to be there was one per opening of Firefox. There are now 3 again. In the habit of opening multiple windows as there seems to be better performance, especially with closing each window when not in use.
