Diễn đàn hỗ trợ Firefox

Went through all the suggested fixes, reset printer but all the printer does is feed paper (two sheets for a single page doc). I converted the webpage to a PDF and it printed.

I am beta testing windows 10. I use both a hp laptop (dv77128nr) and a desktop (home made). I use a hp officejet pro8500 a910 printer.

When using firefox I get only blank pages while trying to print from within the browser. Only using firefox. Chrome works fine. IE works fine. If I boot to windows 7, firefox works fine. Can you help or should I report this to Microsoft?

Thanks for your help.

ps. Tried resetting firefox. Haven't tried a new install.

Hello... I installed Win 10 Tech preview yesterday and re-installed Firefox as i find it the best browser. I now have a problem of not being able to watch videos within web content. It asks to install Flash but when you click on link for download, it is empty. Any help or ideas on how to overcome this issue? Many Thanks

After updating to build 9860 I am unable to print. The printer just feeds blank pages. I don't have any issues printing from chrome or IE, as well as any other program.

I tried all the steps here https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox Still unable to print.

I'm testing Window 10 and when I try to use my ISP's webmail I get this while trying to log in:" ! Error Email Serve is not Allowed" and can't log in. On the same computer I can log in fine with Internet Explorer so I believe it to be a Firefox problem. My ISP support said they have no issues on their end and all my other computers can log in fine as well.

This is how my family stores their respective Firefox profiles on the family computer:

********** [General] StartWithLastProfile=1 [Profile0] Name=default IsRelative=0 Path=E:\<user>\Mozilla\ff\ff1 ********** The "E:\" partition is our user data partition. We keep Mozilla profiles there for two reasons: 1. Ease of backup. No need for YET ANOTHER special back-up rule. 2. All of the operating systems on the machine (we usually are running several via multi-boot) can use the same profiles, which hence do not become unsynchronized across the various operating systems. We do the same thing for Thunderbird: ********** [General] StartWithLastProfile=1 [Profile0] Name=Bellsouth IsRelative=0 Path=E:\<user>\Mozilla\tb\tb1 ********** So now we're evaluating Windows 10 Technical Preview... not on bare metal, but rather as virtualized by VMware Workstation 11.0, which treats partitions other than C: as mapped network drives. Hence, our profiles now look like: ********** [General] StartWithLastProfile=1 [Profile0] Name=default IsRelative=0 Path=\\vmware-host\Shared Folders\E\<user>\Mozilla\ff\ff1 ********** [General] StartWithLastProfile=1 [Profile0] Name=Bellsouth IsRelative=0 Path=\\vmware-host\Shared Folders\E\<user>\Mozilla\tb\tb1 ********** Note that VMware Workstation maps external partitions via "\\vmware-host\Shared Folders\<drive letter>". By the way, apps running on Windows 10 TP virtualized in general have no problems accessing our E: partition in this manner. Thunderbird is able to find and use the non-relative partitions without issue. However, Firefox fails to do so. After experimenting a bit, this is what appears to be happening: 1. Firefox appears in the Process List for less than one second and then disappears. 2. Firefox generates the error: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." 3. Click the "Close Firefox" button. 4. Firefox generates the error: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." Well, that last error is infamous... but we learned long ago how to find/fix missing profiles. This is something else altogether. Is the problem simply that Firefox cannot have profiles on mapped network drives... but Thunderbird can? Or is there some other issue lurking here? Thanks in advance for your assistance. Best regards, ...milo47 P.S. I'm writing this on Firefox on Windows 7 / SP1 / Pro / x64 on bare metal... not under Windows 10... so the Troubleshooting Information is misleading. Obviously, I cannot run Firefox yet on Windows 10!

But, for what it's worth, I don't use many plug-ins, and the version of Firefox on Windows 10 is absolutely up-to-date.

I've been using nightly on windows preview for a long time, I reinstalled several times and it worked well. Recently reinstalled windows and logged on my sync account and found nothing synced. I checked the status at https://status.services.mozilla.com/ , where I found nothing wrong. After that I installed ff mobile on my phone and sync, only my recent added things synced.

...well...so is there some method to get my bookmarks back?

I was using a proxy before and this time I've got no access to it for I'm in China... Will the location affect which server I'm connecting to and in turn change what I got synced? If so can I fix the problem by modify about:config or sth. like that?

Firefox nightly 38.0a1 , on windows preview 9926

If I have multiple windows open, and I click on View, Toolbars, and deselect one of the toolbars, EVERY window open has that change set to them instead of just the window that has the focus. It used to not work that way - deselecting a toolbar would only change the window that had the focus. I think it changed around V30 or so. Is there a setting that can be used to revert this behavior? Thanks.

Hi

I am currently beta testing with Microsoft Windows 10 Technical Preview for Enterprise beta build 9926 which the latest release version.

I am having issues downloading the Adobe Flash Player download from this site. I keep having errors from Mozilla Firefox 35 and Firefox 35.0.1.

It block this site:- (please see the screen capture file)

I suspected this is a Bug with Mozilla Firefox. It too didn't work with Quickscan Bitdefender.

Hey!

I've been using iCloud Bookmarks on my PC for a long time, with Firefox. It has always worked like a charm. Of course it hasn't been like using my Mac with iCloud, but it works. But a couple of weeks ago it started to make my Firefox crash. I don't know if the problem is some recent updates by Firefox, or what's wrong. Has anybody experienced something like this?

Clicking on tabs is sometimes not registered, clicking on forms/links and web page elements in general is sometimes not registered. Roughly every fifth click is not registered. Safe mode doesn't help. Other apps are just fine. Running Windows 10 (10041) and Firefox 36.0.4.

Hello mozilla support, Okay, I am 100% sure of my "master password" which was set up approx 5 minutes ago. it is: Nov/01/1988 I would appreciate any input! Thanks

How can I restore the items in the Recently Bookmarked? It has reset itself twice now and only has some very old bookmarks.

I can restore a saved profile, but this is reset by Sync, so I have had to delete my account and restart it again. This saves a good profile, but after a reboot, the Recently Bookmarked item revert to old ones (4+ years) again.

I am running Window 10 Ver 9926.

Thanks

Hi guys

Is there way to change loading spinner for FF version 37 using userChome.css ?

Here are some nice CSS loading spinner.

Thanks !

I have a suggestion. I would like for browsers to connect securely via https first by default to websites. When the browser checks that https is not supported by the website, it should downgrade to http, so do invalid certificates. This will prevent downgrade attacks and make HSTS headers optional. Browsers for years have been connecting to http by default, which I feel is a security risk. A kind of design flaw. Is an option to connect to https first by default a good idea?

get message from other there are link:
