I am trying to get to a specific port and Firefox blocks the access, https://x.x.x.x:xxxxx. This is the message:

This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection.

How can I allow a specific port?

Hello everyone, sorry for the long post.

For the last 3 days, I have been experiencing a very frustrating issue with videos posted ONLY on Facebook.

Every time I try to open a Facebook video, the Facebook player opens (the one where you can see comments and likes on the right side), and Firefox gives the impression that the video is loading. But after a while, a 'cross' appears in the middle of the screen, below which 'No video with supported format and MIME type found' is written [Kindly refer to the attached screenshot].

Prior to this problem, I had NEVER, in 2 years, experienced any issue whatsoever with playing ANY videos on the Web. Firefox just suddenly decided to stop playing Facebook videos.

WHAT I ALREADY TRIED: - Reload video pages and play them again (FAILED) - Clear cache, cookies and restart Firefox (FAILED) - Start Firefox in Safe Mode (FAILED) - Uninstall Flash Player, try to play videos with the default Firefox player (any video on the Web would play, but Facebook videos FAILED) - Enable the Open H264 Cisco codec (FAILED) - Changing a few values in about:config *(such as media.directshow.enabled) to true/false (FAILED) - Refresh Firefox from https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings (FAILED)

ADDITIONAL INFORMATION: - I use Firefox 35.0.1 and have no other browser (besides the default Internet Explorer 6 which I never use) - I use Windows XP SP3 Professional - I have not downloaded/installed any software/extension/add-on which could have caused this problem

I still love Firefox, and have no intention of migrating to a competitor's browser, which is why I hope a prompt solution shall be found. As well, I am not considering dropping XP SP3 anytime soon; it is very stable and fulfills my requirements.

Thanking you for your time.

I understand the newest version of Firefox offers support for WebP images, which is cool and great... but not when I need to download those images for use on my computer. As an artist I need to be able to save things as .jpg or .png for my art programs (or even preview) to be able to open them. Is there any way to make this an option, or to not default to webp when saving images?

I've also tried changing the extension on the file using the "all files" option but it just corrupts the file and won't open them.

Firefox will not open. I tried every single troubleshoot recommendation, and it still won't work. I thought it may be under the "corrupt profile data" troubleshoot article, but when I followed the recommendations to change to a new profile, the profile manager would not open or run on my computer--as if it never existed. I tried downloading a different browser, and as soon as I imported my firefox data, it started misbehaving in the exact same way.

This is getting extremely frustrating. Anybody know what to do?

This has just started happening: every time I try to print from a remote website (thetimes.co.uk) I get this message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

It is not the website, as the request works from Microsoft Edge.

I can't see any changes to the parameters which might have affected this.

Any ideas please?

My Firefox crashes when trying to open 75% of web pages. I get the windows standard "Firefox is not responding" window after it freezes while trying to load the page.

I have singled out the problem to be the Shockwave Flash (11.5.502.149) plugin as everything works correctly with this disabled.

I have tried updated flash, uninstalling and re-installing it and the same with FF but nothing seems to work so far.

I have tried nearly everything I have seen suggested so far, but nothing seems to work. Firefox started hanging and lagging randomly a few days ago. When scrolling, hovering over buttons, clicking and typing, there tends to be a half-second or 1 second delay. Youtube videos and other video websites are basically unwatchable because they lag so much.

So far I have tried:

- starting firefox in safemode - resetting firefox - using hardware accelleration and not using hardware acceleration to see if there was any changes. - disabling all plugins and extensions and disabling each one-by-one to see if any took up a lot of memory usage. (Firefox memory usage was sometimes over 400 Mb) - downloading a freeware program called "Firemin" which apparently stops memory leaks when used to launch firefox. (Memory usage went from 350-400 Mb to 4-8 Mb !) This helped slightly when watching youtube videos but not with any other hanging and lagging problems.

I'm currently using Firefox 22.0.

Please if you have any suggestions respond because I do not want to have to resort to using Chrome. I am too used to using firefox and don't want to lose my bookmarks.

Hello, I have this problem were whenever I try to type in something into the search or addresys bars, nothing happens. It's like the enter key isn't working. There is not usual picture next to the search bar (the one that shows you what search engine you're using. If it's google it shows a "g" next to the bar). Instead there is just a picture of a blank page as a placeholder. When I try to go in and add a new search engine by managing the search engine list, there is no option to add a new search engine. I have already tried going into the firefox folder on my computer and deleted the formhistory.sqlite file that is the supposed problem. No avail. I have even gone so far to delete and reinstall firefox to my computer. Well, that didn't work either. So I waited until the next update to see if my problem would be fixed THEN. I am currently on firefox 19.0, which is, as of writing, the most current version. I have tried restarting firefox with all addons removed. And for good measure, I deleted anything that ended with ".sqlite" in my firefox folder. I have tried to get the the about:config menu but do not know how considering how my address bar refuses to search. The greatest thing is that my address bar can still remember all the sites I've typed into it before, but for some unknown reason, cannot take me to any of them! I really don't know what to do next. I can only suppose that I could try completely deleting everything firefox has stored on my computer, as I don't know if just uninstalling the program actually did that. Other then my search bar problem, firefox has been acting fairly normally besides a few minor hiccups here and there. I am trying to remember if I downloaded anything before my search bar problems started or not, but it is always a possibility. I did download the firefox beta for windows 8 metro mode but I can't remember if that was before or after firefox started acting up. It's possible considering that softonic thought they were being really nice by including fbdownloader for free with my firefox metro browser. I am now no longer using softonic ever again. But that's all the evidence I can think up right off the tip of my head. Sorry if this was kinda long, and if any of my description isn't clear or make sense please ask and I can try to verify. Also, if I haven't said this already, my search bar is only not working in firefox. Chrome, Internet Explorer, and Safari are all working fine. Just my luck, I guess. If anyone could help me out, I'd be much obliged. Not being able to use the address bar has been really inefficient. Thank you.
