Firefox Support Forum

Out of suddenly, all of my add-ons expect Adblock Plus disabled and I can't enable them, and I didn't change nothing on my laptop at that time. I tried to do Troubleshooting Information, restart my laptop, uninstall and install Mozilla twice, by deleting even all files about Mozilla, but nothing worked. I even tried to do a system restore, but it don't worked because it has a problem in a file! Useful info: When I install again the Mozilla and I install again the add-ons, they are enable and they are working fine, but when I close the browser and open it again, the add-ons are disabled again... And I don't know if that means something, but I have also problem to do the Windows Updates the last week, it can't complete. I have Windows 7 x64 and the lasted edition of Mozilla Firefox. Any ideas?

P.S. English isn't my first language, so sorry if I did any mistakes.

My Addons are working okay, however when I look at the about:addons page the list only shows blank spaces where addons should be, only a blue highlight shows if I click on each addon.

This is the same for my Plugins and Themes.

I have tried deleting some files in my profile as suggested by others on here with similar problems but none work.

MY flash video downloader add on dissappers . Every now and then i have to install that addon again and again. I am using winxp on my PC. This addon uninstalls automatically every now and then i have to download and install the addon.

I did the update online thru Firefox, however have no way of determining whether or not it was successful. Noted that Web of Trust has an update of 12--8-15, however when I click on the icon "check for updates" , nothing happens. The icon for the WOT is there on the upper right portion of the tool bar.

How do I know I have the updated version of WOT?    What does the "refresh" link do?

I can no longer visit local town sites where I read news, and I can't view most sites where I read about science or weather. In example, this site will not load on Firefox claiming it does not exist but I can see it on Explorer: augmentinforce.50webs.com

Whatever is happening is a change that just bam occurred. I am sick of it.

Hi, I find this chrome video screenshot extension very useful: https://chrome.google.com/webstore/detail/video-screenshotter/ppkojackhibeogijphhfnamhemklmial . It allows me to screenshot a video from practically any website. But I am trying to get rid of chrome and stick to firefox. Is there any firefox addon similar to this? I've looked everywhere.

I had a system crash, probably with Firefox opened.

After restarting PC and starting Firefox, most of the addons I have had lost all of their settings and were reset to default - Tampermonkey lost all the scripts I had installed, uBlock lost all settings and rules, etc. Weirdly some extensions kept portions of their settings, like TreeTabs saved tree structure despite also getting reset to default.

Additionally Firefox also got its own settings reset to default, while the tabs from my session and bookmarks were saved.

Is there any way to recover addon and Firefox settings, is there any backup of them?

When the downloadhelper icon animates, I click on it as usual if I want to capture. The button operates normally, displays the video name and I click quick download. Nothing downloads, the library says no downloads for this session. However there is an icon in my download folder, but nothing plays -- there is no download. Everything works fine, except there is no download. Version 36?

I previously used an add-on that would preview a web page when hovering over the link with my cursor on the current web page. The web page would pop up and then disappear after I removed the cursor form the popup. Can anyone tell me the name of the add-on?

everytime I start up firefox It asks me to verify my addons. these are adblock plus, adblock plus pop-up , Ageless, clean links, google privacy, https-everywhere, and a us spelchecker dictionary. plowed trough the community answers and tried about everything: refresh, delete and reinstalled, one addon at the time see if there is a problem there, reset preferences,Prefs.js, User.js and Sessionstore.js,extensions.sqlite, extensions.ini, extensions.cache, extensions.rdf fix, firefox properties are correct no admin startup ect. so in short tried about any solution out there. any way to fix this, and would downloading firefox beta help (aurora)?

thanks

I have been an avid user of firefox since it's inception, I enjoy it's accessability, user friendsliness and have never had a use for customer support (until now). All of my downloaded firefox themes work, switching between them is no problem. I can add and remove add-ons with no problems aswell, but the moment I close firefox and start a new session (sorry, let me back track a tad, I customize my toolbar on a regular bases, I like the functionality and it makes it more personal). Ever since the mid February update every time I close firefox and reopen it my my add-ons in the toolbar are invisible and unusable. There isn't even an information pop-up when hovering over where they should be (technically they are still there). I'm running Windows 10 (fully updated just like all my programs). I took a snap shot of this message to illistrate my point, both my Ad-Blocker and Flash Downloader add-ons appear ro be missing and yet I know they are next to the library button.

And I was only to re-enable three. This happened with NO changes to my browser or extensions; nothing was updated, and I didn't tweak any settings. One of the ones I can't enable is by the same creator as the ones I can (TrendMicro; others I can't re-enable include RealPlayer and Yahoo toolbar). I'm a bit concerned as it is a security measure I can't re-enable. While the one I'm most concerned is a Tumblr add-on/extension (XKit, The Extension Framework For Tumblr), because I don't want to install 500 new extensions to deal with one problem at a time, when I had a perfectly good extension that deals with all of them and already has my settings saved (including some important things archived). From what I've seen, the creator has to get the extension "signed" or whatever, which presents a problem as the last available xkit update I saw was from last year (2014). Is there ANYTHING that can be done to fix this???

Hello,

Suddenly, when using the screenshots tool, it doesn't save save my shot when I screenshot it and click on the "Download" button anymore.

Nothing happens and I can't see anymore that blue down arrow beside the URL bar.

Windows 7 with all updates Firefox ver 43.0.3 Self-Destructing Cookies (SDC) add-on ver 0.4.9 Firefox set to remember history SDC is enabled and working No other add-ons enabled

Problem: SDC icon not visible

I have used SDC for a couple years and recently changed computers from XP to Win 7. The SDC icon is needed to easily change settings for each website I visit.

I mistakenly downloaded an extension believing it to be a genuine Firefox one. It takes my to myemailxp.com Now I have a dialogue box which tells me my extension has expired, asks me to renew it, and prevents me getting into the browser. I just want to get rid of the extension and get back to basic, English, Firefox. How do I do this?

I have two Windows 10 PC with Firefox.

Since several weeks in forms like gmail compose or facebook messenger or hotmail both sujbect and message, I cannot type the letter q in lowercase.

Fine typing Q but no q

I tried to find any solution to this but no results. I found a similar topic here with letter Q instead. I followed the steps but no luck as well. (Cannot type letter Q (weird bug!))

The issue is simple, typing q doesn't type anything. I can paste the Q from clipboard and works fine (this how I survived)

I have Spanish (Mexico) language and Latin American keyboard by default. Tried with the standard English (US) and US international keyboard with the same behavior .

Any help is appreciated.

Hi. I made a dumb mistake and installed an add-on or extension (not sure which) that I was hoping would allow me to view YouTube videos in full-screen. Unfortunately I can't recall the name of the add-on/extension.

The problem is, now every time I open Firefox it opens in "full screen" and NOTHING (including F11) will allow me to access the taskbar, the address bar, or any of the other Firefox controls. I can't do anything at all but view the home page in full-screen! The only option I have is to hit control-alt-delete and close Firefox.

I tried uninstalling and re-installing Firefox and this didn't solve the problem. Please help. Thank you!

P.S. I'm writing this in Internet Explorer since I currently can't use Firefox.

Since upgrading to the latest version I am trying to find replacements for the newly disabled add-ons. I first tried this on Friday the 8th. The same problem has been happening all weekend including today and I imagine since I installed this version. The exact wording is downloading and verifying add-on.

A "add-on" called Bitdefender but has nothing to do with the real Bitdefender now obliterates the upper part of Firefox. A new installation of Firefox does not help. It is still there. It shows as Bitdefender /Devicarus when you look for add-ons in Firefox.
