Sometimes, when I try to open Firefox, it shows an error message saying that the file can't be found. I have to close the dialogue box and try to open the browser again and again until it actually opens. Typically, this happens in the 2nd or 3rd try but may take longer. Also, this doesn't happen every time I try to open Firefox. Is there a problem in the installation? The program itself works completely fine when I get it to open.

Something is opening new tabs and windows in Firefox and making them active. I suspect cookies. I tried the 2 ways to remove all cookies. They reappear. I have reset Firefox. I have cleared all cache. I have run scans from Zonealarm and PC Matic. So three questions. Is something in the registry causing this? Has anyone had this and know what caused it? How do I remove all cookies? Thanks for your time. Keith

After deleting prefs.js file Firefox does not create a new one.

Firefox does not save any of my settings so i tried all the method described in the following articles:

https://support.mozilla.org/en-US/kb/how-to-fix-preferences-wont-save https://support.mozilla.org/en-US/kb/how-to-fix-preferences-wont-save#w_unable-to-save-any-preferences-or-settings

finally I uninstalled FF completely, deleted the FF installation directory and moved my old profile. Reinstalling FF did not help in anyway. After reinstalling, the preferences were still not saved so I deleted the profs.js file. When I start Firefox it does not create a new profs.js file adn of course my setting are still not saved

What can i do? change? I'd rather fix this than install chrome instead...

Firefox 34.0.5

When using a large number of tabs, around 300 inactive and 30 active tabs, when the currently selected tab is a tab on the far left side of the tab bar, attempting to scroll to the end (far right) side of the tab bar will often cause scrolling to freeze momentarily, and then reset to far left, to the currently selected tab, and continues scrolling from the beginning of the tab bar, making it unnecessarily difficult to scroll to the end of a long tabs bar.


This occurs when scrolling up/down with the scroll-wheel on a mouse, when scrolling up/down/left/right on a touchpad, and when scrolling using the left and right scroll buttons in the tab bar.

When viewing pictures in a gallery (on a website that I have used nearly every day for the last few years), it doesn't advance to the next image when I click on the arrow that should take me to the next image. It works with other browsers, but I prefer Firefox.

Running Firefox 34.0.5 Sometimes, but not always, clicking in the tab bar will open the wrong tab. Instead of opening the tab selected, it will open a tab all the way to the left side, in the corresponding position, rather than the tab I intended to click on.

For example, this image shows the tab I click on. http://puu.sh/eAfsP/7ddac08d41.png

And this image shows the tab that firefox switches to instead. http://puu.sh/eAg4Z/2b4f441564.PNG

Notice that it has instead moved to the far left end of the tabs list.

It may be significant to note that my firefox is currently running with around 300 individual tabs, around 30 of which are loaded at any point and time; however, please do not attribute the problem to the tab count without a reason, because this issue has never occurred in any previous versions of Firefox.


[Solved] There was a conflict with an extension that appears to have been resolved.

Firefox 34.0.5

Using the option, [Don't Load Tabs Until Selected], when I click on a tab that needs to be loaded, the tab is automatically scrolled to the far right side of the Tabs bar, as you can see in this screenshot. http://puu.sh/eAhdx/296a80d319.png

Is there any way I can disable this behavior?

Hey, ive read some other threads but didnt notice anything that solves the problem. So yeah, recently, like 3 days ago or so, youtube videos started randomly not loading. I mostly use youtube to play music, got my own playlist, but now the songs try to load for like 10 seconds or so and then skip to other song. Tried playing a song not as a part of playlist, but a separate video. Tried to load, but eventually got error. On read more there were few suggestions, ive tried them all, nothing changed. Deleted cookies and cache. Tried playing firefox in safemode, then youtube videos work fine. btw, i guess i should mention, that i use adblock plus so that i could play the playlist and not get those 10 minute ads between every song. if i manually disable adblock, nothing changes mostly. Though 1 time the video started with an ad before the song but only once. if anyone could help me i would appreciate it. If u need any more info ask away :) (so far it seems like only videos from my playlist fail to load)

I am afraid that my technical knowledge is limited so at some point when downloading iPlayer it asked a question about file association which stumped me. After pondering for some time I decided to associate it with Firefox, this was a mistake. It resulted in when I tried to download a TV programme from iPlayer it literally opened several tabs a second. I un-installed iPlayer and downloaded it again and it never this time asked any question about file association. It downloaded correctly, but it still displayed the fault in question, the ever multiplying tabs.

Firefox is my default browser and I am running the computer on Windows 8.1 64 byte. For purposes of downloading I use IDM.

I would be most grateful for your help in this matter.

Regards,

John Daniels

When I click a new tab, the newtab screen comes up populated with a lot of sites, which I have deleted, leaving only the search bar. I followed the instructions regarding about:config, but the new tab still opens in that search bar in the window instead of in the address bar. How can I get my cursor to be in the address bar of a new tab, ready for me to insert a url?

My new (11/2014) PC came with Internet Explorer pre-loaded. I set up Mozilla as my preferred homevbase and then tried to install Adobe Flashplayer. After failing I found that it is already installed as part of the Exporer pre-load. However, I cannot use Flashplayer via Mozilla: it seems it is only available via Explorer. But, clearly, I don't want to use Explorer (I don't trust it).

How can I get Flashplayer to work on Mozilla as well as, or instead of Explorer, please?

Since DL the latest ver 34.0.5 FF, I now have to move my mouse for anything to happen. Also , when I play a video or live TV site the sound is good but the video is choppy and I must constantly keep the mouse moving for it to play. This has never happened before this download. So far most of the fix suggested has no fixed the problem. Currently running Windows 7.
