Firefox Support Forum

Hello there,

I've had this problem for a long time, and I've done most everything suggested in other forums regarding this matter. I've disabled "disabled protected mode, disabled hardware acceleration, made sure everything is updated, and nothing works. Unfortunately, this makes Firefox so unusable that I've had to switch to another browser for the time being, but it's having it's own issues. Very frustrating! I like Firefox and would like to have it working, but this "shockwave flash plugin" problem has been a persistent problem for the last year.

I've seen many other users who have not been able to fix the problem via the above suggestions, so--what's the verdict? Is there something else I can try?

Cheers

UPDATE! This question is not marked as answered, as the issue is a new 'feature' of Firefox 22, and if you read all the comments you'd see that. Clearly, with the large volume of 'new' answers coming in saying the same thing over and over, people aren't, so I'll say it here: THERE IS NO NEED TO ANSWER THIS QUESTION ANY MORE.

I recently asked about my UI being big and fuzzy, and managed to get that fixed in the about:config, but websites are still big.

For some reason, the default zoom (ctrl+0) is at 120%.

I tried the FullZoom and NoSquint addons, but both had one issue. They messed up the top level image view (which for me works with the old default image style addon) and made the unzoomed image a bit bigger than my screen, and the magnifying glass icon which should appear with a + or - in it when I mouse over the image is just a regular mouse pointer instead.

How can I reset the default zoom to be 100% (or preferably about 80% because even 100 seems to be overcompensating for my high dpi screen) without an addon messing up my default image view?

Further details. If I disable the 'old default image style' addon, the top level image view works fine with the NoSquint or FullZoom addons.

Whenever I visit a page that contains even the smallest of Flash objects, Firefox stops responding briefly and then a dialogue pops up to say that Shockwave Flash has crashed. I have tried all of the fixes I have found on other questions: I have reset Firefox, run it in Safe Mode, disabled all extensions, reinstalled both Firefox and Flash, downgraded both Firefox and Flash and turned off Flash's "Protective Mode" etc. The problem only seems to have come about after I upgraded to Firefox 20 yesterday if that is of any help. Flash also crashes on IE and doesn't work properly on Chrome (YouTube does not play sound for example). I have run out of ideas and I was wondering if anyone has anything that I could try. Thanks in advance for any answers!

I can't open Gmail anymore...saying: This problem can sometimes be caused by disabling or refusing to accept cookies. Instructions talk about a location bar and about:config page? Like it's just assuming everyone knows what and where those are...

and furthermore, I see that almost all the question threads asking about this have been closed. I've downloaded the suggested add-on, but my question is ..what changed? Firefox was the best at blocking popups but now it's as if the popup blocker is nonexistant. I have not changed settings, but popups started becomming increasingly abundant, I have checked and unchecked and rebooted with no improvement. It's not an occasional popup ad, literally every third click I make (even within one window) causes some popup ad to appear....I've counted. Has something happened to firefox or have the ad guys just gotten smarter about going around popup blockers in firefox? Either way, PLEASE FIX THIS. Otherwise, why have the option of checking a popup blocker in Options? Thanks!

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.

I've noticed that on sites like Twitch or Youtube, that the larger the window size is for higher quality streams of video content, the more it tends to stutter and thrash the disk. Since Twitch and YouTube are both supporting 60fps videos now, it's very easy to tell when the video stutters.

If I shrink the window size down, the problem isn't fully alleviated, but it does get better. With Chrome, I don't really notice any slowdown, yet it's using the same Flash version.

Any thoughts or ideas on what the problem might be?

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.

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)

Last week, I downloaded Mumble, a voice chat program. I was playing World of Warcraft at the time, and needed to download Mumble on the fly, so I was insufficiently careful and downloaded an extension, Websteroids, at the same time. Websteroids highlights words in text documents which, when scrolled over, lead to advertisements. The claim of the Websteroids website is that it turns a webpage into a meteoroids game.

I have repeatedly disabled and removed it from my extensions list, uninstalled and reinstalled Firefox, deleted files with the Websteroids name on it, uninstalled it and Mumble, and any other files/programs that I could find from that date.
I've run my antivirus program (AVG), spybot s&d, and lavasoft ad aware and followed the advice from their scans. Nevertheless, Websteriods keeps reinstalling itself without warning.
I have restarted Mozilla in safe mode and I've also deleted anything I could find from the publisher, Creative Island Media, LLC.
The next step that I can think of is a system restore. Before I do that, is there any other less drastic step that might work? 

Thank you

This started just about a month or so ago. Almost every website I visit Firefox either lags or outright stalls, giving me the (unresponsive) notice at the top or unresponsive script error messages.

I have tried every suggestion I could find in the help, including "Firefox uses too much resources", "Firefox hangs or is unresponsive", and "Unresponsive script - how to fix". I have cleared all history, cookies and cache, reset Firefox, reinstalled, everything I can. I disabled all my extensions and add-ons one by one to see if they impacted, I made sure everything including Firefox is up to date. Nothing has changed the behavior.

Any help here would be appreciated.

I was trying to register a digital signature certificate on www.incometaxindiaefiling.gov.in. When the site requested to run Java applet JRE7, which I allowed. But then the small window pops up with the following message;

Application Blocked for security reason The Application cannot be run. Name: StoreCertificate Location: http://incometaxindiaefiling.gov.in Reason: Your security settings have blocked a self-signed application from running

When viewing a user's photos on instagram.com/user, I click on one photo and it opens in a new tab (as opposed to popping up in the same tab in middle of the screen). Then, when I 'X' out the new tab and return to the old one with the rest of the photos, I cannot click on anymore. I have to refresh the page each time I want to view a new photo. This does NOT occur when I view the instagram.com/user page using Internet Explorer. Shockwave Flash and all other plug-ins are up to date. I just noticed this issue with Firefox's newest upgrade.

I just installed Firefox's newest version 21. I went to a website which required flash and it said I did not have flash installed. So I installed flash from adobe's website and it said it installed successfully I went back to the website after restarting my browser and it still did not work. I restarted my computer and nothing. I reinstalled flash again and it still does not work even though adobe is telling me it installed successfully.
