I just updated Firefox and ended up with Quantum. How in the world can I get my previous version back, and get rid of Quantum? I have never been so disappointed in Firefox as I am right now. I never, ever would have clicked update if I knew I would end up with this.

Mozilla at https://support.mozilla.org/en-US/kb/add-on-signing-in-firefox?as=u says that I "can still install [an] unverified add-on at [my] own risk"--but it doesn't say how. How may I use an add-on that in version 40.0.2 Mozilla has disabled for being "unverified"?

I tried to use Firefox in three different computers but only in the one with over 4 GB of ram is usable. Why it uses so much RAM and renders so slow? Specially the scroll is really laggy.

I tried clean installations but they do not fix the issue.

When opening Firefox and Chrome and playing a video in YouTube, Firefox uses over 500 MB while Chrome uses less than 300 MB. Both with the same single addon.

Is there something that can be done to use Firefox in computers with less than 4 gb of RAM?

My Firefox on a windows 7 HP laptop updated today (June 25th) and the zoom adjusted, changing the font size, as well as icons and zoomed in on websites. I noticed in the list of changes for the program it says "improved rendering on high-res displays" is this the problem and is there anyway I can disable this? I was quite happy with the resolution before, and find this tacky and annoying...

For the last few days my Firefox does not display the downloads window. I have tried to follow the suggestion set out in Firefox Help ie Tools --> Options --> General

But my General Tab doesn't show under Downloads the option to check the box "Show the Downloads window when downloading a file". Under Downloads, the only option shows "save files to Downloads" and "Always ask me where to save files".

Any suggestions on how I can get to --> Downloads the option to check the box "Show the Downloads window when downloading a file".

Thank you in anticipation

I have Firefox 30.0. My new tab was just Google, now it is nine different web pages which probably represent my most used webpages. I don't like this setup. I just want Google each time I start a new tab.

I would also like to stop this page from being hijacked so regularly. It is incredibly annoying. How can I stop changes being made without my permission?

I've had about 5 different pages as my new page in the last two weeks. I've removed some programs from my computer, but it's still happening.

I tried to do the about:config thing, but the page that shows up (browser.newtab.url) says that it is the default of about:newtab

Can anyone please help.

Sorry guys, i am disgusted with this upgrade. 29 does not seem like a good ui update at all. The menu bar looks really bad and so does the tab. Furthermore this does not solve my other tab issue i have either in another question i have asked.

How can i revert back to my last version with all my tabs/windows/history restored? I will do a system restore if i have to and then cancel all automatic updates. I honestly dont care if it gives me a bigger security risk.

Heuristics will allow addons to keep working after upgrading they said. Firefox won't break your addons they said.

19->20 Firefox broke the addon (though installing the identical version again got it working again) 20->21 Firefox broke the addon again.

https://addons.mozilla.org/en-us/firefox/addon/SnapLinksPlus/

While they're trying to get the addon working, and for some a beta version works, for those of us who need these addons it means we need to downgrade Firefox. What's the best way to go about it? (PS: I don't care about security or what new features are in FF21 - I'd rather have working addons)

This is still prevalent and I have had to disable the plugin for shockwave player. Similar was happening with adobe flash player but since the Firefox update it isn't happening as much. Is there a solution to solve this or is it a Adobe issue that they need to fix.? When it hangs or crashes it sometimes takes out downloads. I rolled back to the older dowload box because if I closed the browser it took the downloads out. Downloads don't crash as much with the older download box but with Firefox 20 ( with the new download style) the downloads died quickly with an error message the "file could not be read"

Also, is it okay to enable my add ons now, they were accentuating the problem as well.

As of midnight 12/12/14, Firefox started blocking plugins (in this case, Adobe Flash and Java Deployment Toolkit, possibly others as I've just been to websites that use those), saying that they're out of date. When I click on "Update Now," the Plugin Status page tells me that all my plugins are up to date. (I'm currently running Flash 15.0.0.239 and Java Deployment Toolkit 10.71.2.14, for the record.)

I get the point of this feature, and I really don't want to permanently turn on "always allow," but having to click two "allow" prompts every time I load a website that features Flash is quickly making web browsing intolerable. I'm on the verge of switching to Google Chrome over this.

Hi,

I had an automatic update install to firefox around 2 weeks ago. Since then it has gone from being the best and fastest browser on my computer to the slowest.

Even just typing this message there is a massive lag between me typing and it appearing on screen. Prior to the update it used to run perfectly. If I try and clear the search bar to type in a new address it can take 5 - 10 seconds or won't do it at all so I end up typing into what's already there! Basically every action I take with keyboard or mouse has a delay attached to it.

I have so far tried to reset Firefox option which has made no difference.

Am running Windows 7 Service Pack 1 with 4 GB of RAM. Over half of hard drive space remaining.Chrome which I also have on my PC is running perfectly normal. If possibly I'd like to carry on using firefox! :-)

Thanks for any help.

Where's a 64-bit Firefox?

This question was probably asked before, but I guess it's important to keep asking so that the developers will realize that this is actually important.

I'm running a 64-bit Windows 7 for a few years now. I'm not sure if they even make 32-bit processors anymore. Any new PC you see advertised comes with Windows 8 64-bit. Both versions of Windows come with 64-bit IE. To be honest, the 32-bit IE is not only included, but is also default, but this is for the sake of backward compatibility. Opera is available in 64 bit, and so is Firefox, but only for Linux and Mac OS.

So where's the 64-bit Firefox for Windows? For years we've been hearing about plugins. Now, both Flash and Java are available in 64-bit. 64-bit Nightly works perfectly, I run it for years without any problem. Third-party builds also exist and work fine. So why not make an effort and promote the 64-bit Nightly higher up the production chain?

Sometimes we hear about "other priorities". But let's be honest here - what other priorities? I'm not sure why would I care about HTML5 - YouTube already works, and I don't see why should I care if it's in Flash or HTML5. Same about most other "cutting edge" features. I don't think I notice them. But I do notice that I have to run a 32-bit application on a 64-bit machine. Some people ask - what's the advantage of using 64-bit Firefox? I ask, why should I run a 32-bit application on a 64-bit machine? Just because it works? That's just not good enough.

So, enough with the excuses, just do it! That's what people are waiting for, not the "Firefox OS" (now why would I buy anything from a "proudly non-profit" company?)!

I'm not sure what I did to cause Firefox to do I GUESS a BACKUP. Since I now have a folder named "Old Firefox Data" what do I do with it? Do I need to somehow re-instate all that is in this folder back into my Firefox Browser? Or, do I need it at all? What am I missing here? No explanations, no guideance, no direction as to what to do or how to do it from Firefox or Mozilla. I can't even tell for sure IF I AM MISSING ANYTHING WITHIN MY WORKING FIREFOX BROWSER NOW THAT WAS SAVED IN THIS BACKUP orrrrrrrrrrr not? lescot lescot@sbcglobal.net
