Every time I go to Yahoo.com and try to sign into my mail accounts, I get the Recaptcha. It may ask me to click on all cars in the pictures. When I do that I notice the "Continue" button is superimposed on the pictures of the cars and then when I try to click on the "Continue" button, I get a circle with a diagonal slash mark through it. Yahoo won't help me with this until I pay money. This problem started when their pay for phone tech program started. Please help!

I am a computer dummy. Firefox is installed in our Windows 8 computer as our browser. Whenever we use it, a very annoying thing called Default Fire Fox Developer tools comes up at the bottom and takes up half our screen. Sometime it lets me hit esc. to close it but then it just pops back up. We use our computer for the net, e mail and social media alongside learning sites for our kids. How can I get rid of this thing? Please help me and explain it like I am 6 .

Just updated to Firefox 29.0 and the tabs not currently viewed are now the same colour as the background above them at the top. File, Edit, View, History, Bookmarks, Tools, Help are distinguished in a different colour though. I've checked but found this is the default theme. But it wasn't in 28.0, the tabs have always been a different colour to distinguish them. How do I tell Firefox to make the tabs a different colour to that above them? It's very annoying/disconcerting and just looks pretty awful. Not had this problem with updates changing the default colours before. Would have thought it's a no brainer for the default to have the tabs a different colour to distinguish them. Don't want to muck about with other themes, just want it like the default use to be. Thanks.

I'm having some trouble with javascript menus (or what I believe are javascript menus). Whether it matters or not I am not sure, but it happens in both Firefox and Chrome...IE works fine.

Examples of sites with menus that don't work:

1. Orbitz.com: Can't pull down the "Adult" or "Child" menus. 2. toyota.com: Can't "select vehicle" at the top of the page.

I get no error messages. I have started Firefox in safe mode, I have also reset Firefox.

I use Gmail and occasionally receive emails which contain embedded images rather than attachments. These images do not appear when I use Gmail from Firefox, but they do appear when I use Gmail from Chrome or IE. If I forward the mail then the images appear in the forward mail window. Have tried all of the recommended actions but with no success.

When I open Firefox it reverts to the above linked search engine.

That link is to the search engine that has infected my firefox. I have tried several methods to get rid of it. I have gone into extensions and deleted anything that looked like it. I have gone into 'uninstall programs' and un-installed anything that was to do with it. I have ran my Norton 360 scan which has detected nothing. I downloaded Malware Bytes free anti-malware software scanner which detected nothing. I have reset the home page to default but this does nothing. I have tried re setting firefox, no result. Please can you help me remove this search engine off firefox, nothing seems to work and it is very irritating. Thanks

every time, and i mean EVERY TIME i enable flash on firefox 20 running windows 8 it freezes. i disable it and all is fine, i enable it and FF freezes and is totally unresponsive. i have tried everything, running ff in safe mode, totally uninstalling both flash and firefox, nothing works. chrome works fine using it, any suggestions?

this has been going on for a while and i am considering the previously unthinkable and switching to Chrome, i don't want to but waiting five minutes for firefox to open is getting on my last never. the thing is, it only is this slow the first time. after that it is fast as usual. i have tried disabling all addons and plug ins, nothing works. as i said, it only does this when i try to open it up first thing in the morning after booting up the computer. i have a fast computer too, an intel i7 3770 processor and 16 gigs of ram so that is not an issue. i am running windows 8 by the way. i click on the firefox icon and it does nothing for at least a few minutes, then opens. very frustrating. also, i have disabled prefetch as well, no good. attached are screenshots of my addons and plug ins. yes, i have uninstalled it completely and reinstalled, no luck.

I get an error message that says , nsAppShell:EventWindow:firefox.exe... Application E... The instruction at 0x7758e1144 referenced memory at 0xffffffff. the memory could not be read. Click on OK to terminate the program. What's wrong and how do I fix it?

Firefox has been my browser of choice for about 6 years. On 3/16 /15 it stopped working. I tried all of the suggestions. I then completely uninstalled Firefox and Mozilla Maintenance. I restarted and checked my disks and memory. All other browsers: IE, Safari, Chrome & Opera work fine. I installed from Firefox Setup 36.0.3.exe this morning. Same problem. Works for about 5 minutes and then hangs.

Firefox hangs. Doesn't give a clean crash. Doesn't give report. Cannot restart. Removed completely (even Mozilla Maintenance) and re-installed: same problem.

What can I do?

I run three websites. One is personal (www.rossolson.org) and two are for non-profit organizations (www.outpostministries.org and www.tccsa.tc). All have site search through Google, my own site is paid to be ad-free, the non profits are free and without adds because of their non profit status. For a while now, site search does not work with Firefox for the non profit sites but does for the paid site. Chrome and IE work fine. Is there a solution? Some setting to activate? Is this Google's doing?

The Tab on my browser is double sized under Windows 8. I have already searched the forums for a solution and none worked.

Already tried: 1. Safe mode 2. Create new Profile 3. Reinstalled with NO extensions 4. Cleaned out everything entry in appdata/programdata/registry

After everything double sized tab persists.

So I am led to believe that this is some new setting for Firefox where it detects an unknown 'Tablet' mode and sets the default theme as having double sized tabs. -- And just FYI -- I am NOT using a touchscreen. So whatever it is detecting, it is faulty. If you are going to put this in as an option, please add an option to DISABLE it.

When I change to another theme, such as Mx3, it does fix the double sized.

For the past few days Firefox browser videos requiring Flash player do not open but give me the 'crash screen'. It works fine with Internet Explorer because it is built in. I have tried all of the recommended fixes from adobe and and firefox.

I have refreshed Firefox
I have enabled in firefox
I have disabled all plugins and extensions then tried enabling Flash Player
I have uninstalled and reinstalled Flash player a few times
I have tried adjusting Flash player settings
    " deleting FPs cache, etc.

I have not been able to adjust FPs "hardware acceleration" because it won't open in the support pages.

I have: a newer toshiba Satellite L70 (intel i7)

64bit

windows 8.1

I am stumped!

I have uninstalled and reinstalled the current (as of 6/22/13) flash plugin for Firefox. I also have turned off hardware acceleration but my flash player keeps crashing on every youtube video I try.

Crash reports With Hardware Acceleration: https://crash-stats.mozilla.com/report/index/929ae2cc-b007-4dee-900f-a66fc2130623

Without: https://crash-stats.mozilla.com/report/index/ca2d2983-77b4-4ccf-a271-9e48c2130623

Also Firefox just stopped responding when I allowed the troubleshooter, but it did give information after restoring my previous session.

I've tried various methods of sorting tags. None of them really represents the conventional output one would consider "sorting". I've had to, for example, prefix categories of tags in order to get some semblance of order. Lately not even this works very well after going through various updates to Firefox.

Further, there doesn't seem to be anything on the Mozilla website for Firefox that addresses this question. Perhaps my library of Bookmarks is more extensive than most, and those who program the interface have never seen a need to provide this capability to sort tags. In my case, since I've used tags to introduce order and fast access to information, tags have become indispensable to that end.

Maybe the reason this capability is missing is because it is not technically feasible. I would like to know whether or not it is so I don't continue to search for a solution.

With FF24, when I move the mouse over a link the cursor end changes from an arrow to a magnifying glass. While FF is not my main browser, I do use it a fair amount and never saw (or noticed) this before. Is there a way to keep it arrow only? Thanks,

there is already another question with the same problem I am having, but to be able comment on it I needed to ask my own question to register. I am running windows 8. I was using firefox when the prompt came up "firefox needs to update... and will reopen in a few moments". Firefox never reopened Instead I received an error message "C:\Program Files (x86)\Mozilla Firefox class not registered". I have uninstalled, reinstalled, deleted C:\Program Files (x86)\Mozilla Firefox , reinstalled and still receive the same error message "C:\Program Files (x86)\Mozilla Firefox class not registered". When I reinstall firefox it never opens its always comes up with the error message. Any solutions?
