Firefox 技術支援討論區

When I try to attach a file to an email send in Gmail, nothing happens. The upload bar shows no progress and the email sits in the draft folder. The size of the file has no bearing on the problem. I've tried running in Safe Mode and even did a clean reinstall but it didn't help. The problem does not occur with the same accounts in Chrome or Opera; only in Firefox. I've tried everything recommended here, but nothing helped.

I need to install Firefox NEW on an XP laptop. I need the (newest) old version that will install on the XP downloaded to THIS (Windows 10) computer and "Sneaker-netted" to the XP. Then I presume I will be able to download the NEWEST version that will run under XP and do the upgrade. What I received was indistinguishable from the most current version, when I tried to get 43.0.1. Help?

When I signed on to my computer this a.m. and clicked on the Firefox icon from my Task Bar (on the bottom of the page) to bring up my homepage, it wouldn't go. I rec'd a msg stating it "couldn't find" a .dll file or something. When I clicked on the icon on my desktop, it started a whole new page - I lost all my "saved" pages and my "favorites" menu was gone! What happened and how can I get my "normal" Firefox page ?

OK sorry about not getting right back, I ask for help then I don't follow through not the best way of doing this. So I have done some more exploring on this problem. I am not sure what's going on. So I am running dual display on a laptop running windows 10 . Seems to me everything is updated. So up on the main display (external display) it's OK everything seems to be great on it.

So if I go to the laptop display that's where my problem is. So what I have done is on max the window is where I get this problem. Min. the size window goes away if the screen's location is about 1" down from the top of the frame on the screen. If I move it up some just a little 3/4" it seems to be a small drop down window again. If I move it up even more not to the max but just up to say about 1/2" the drop down window gets bigger however it is still cut down with no way to scroll down to see the rest of the window. So what my thoughts are is the over scan of the video is too big? If so how do I take care of it? I hope this helps out. Let me know thank you for your help on this matter. So if I go to single display its all good on the laptop window.

UPDATE: So I have also played with other web browser, Chrome and Edge and I can't recreate it in those browsers. I adjusted the over scan so its not that. I can't get full Images of both displays at once to big of file.

I've been using Firefox for years but this morning it stopped working. the little firefox button just kept moving left-right and never found the page. Eventually I gave up and uninstalled firefox but when I tried to reinstall it, it states that firefox was previously installed and allows me to reinstall. when I do that it always gives an error message that it was unsuccessful.

I can't get spellcheck to work. I'm using Firefox on a Mac. This is true even when using a box with multiple lines.

I have ticked the box in preferences that says Check your spelling as you type. I have a language chosen - English (United Kingdom). I tried installing a different dictionary in Add-ons, but it made no difference.

I've gone into about:config and adjusted the settings in layout.spellcheckDefault and checked services.sync.prefs.sync.layout.spellcheckDefault, which made no difference.

I've read posts that say to right click and look at the dictionaries, but this doesn't work for me (could be because I'm using a Mac). Same with pressing Control.

Any thoughts?

Hi there,

I'm trying to disable insecure ciphers in TLS 1.2 since 1.3 isn't widely supported yet.

I'm using this to determine whats secure: https://browserleaks.com/ssl

I cant find any option to disable these two ciphers:

0x009c TLS_RSA_WITH_AES_128_GCM_SHA256 0x009d TLS_RSA_WITH_AES_256_GCM_SHA384

Thanks :)

"question: says it all. I have gone to "Options' and checked all the boxes and still I get only an abbreviated list of sites that I visit or have visited and this does not change with time. I have been using Firefox for years and this has never happened after an upgrade. For instance every time i want to go to my Hotmail account, I have to type in the URL in the address bar where as I used to be able to hit the drop down arrow in the address bar, a menu would drop down and i could click on Hotmail or Bank of America, etc and be taken to the site.

I cannot access Mozilla via Firefox - issue arose when trying to access add-ons yesterday (25 Jan 2020). Firefox displays the following: "Secure Connection Failed

An error occurred during a connection to addons.mozilla.org. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem."

In order to post this, I have had to access the site via Chromium, which also noted a secure connection error. I have used a VPN add-on to secure the connection and access the site.

I assume this is an issue on the Mozilla server with an expired certificate?

I have noticed that my Flora Terra Website (https://floraterraca.com) sometimes open perfectly but often not.

Should I include some extra code to make it compatible?

My google maps is unable to access my location even though I have allowed location access from Firefox preferences/settings. The blue target button (Current Location) on Google maps is greyed out, and when I hover over it it says that access is not allowed. Even though when I'm in google maps, the Address bar shows that my location access is allowed, as well as in the Firefox settings. I have refreshed the window multiple times, restarted Firefox, cleared all cookies, and restarted my computer. I've also toggled the enhanced tracking protection in the address bar to off, restarted the browser, still not working. Everything in the settings tells me that access is allowed, yet google maps still tells me that it is denied. Has anyone had this problem, or know of a workaround or how to fix this? Thanks! (Working on Firefox 75. with a MAC)

Hello,

I have the latest version of Firefox(?) on my 2014 Macbook Air. I'm using El Capitan 10.11.6 - I'm afraid to upgrade to the latest version. When ever I open Firefox, the following extension pops up in the search window: http://search.anysearchmanager.com/?_pg=32305279-EF96-58E8-AD0D-5C619AE6B900&affid=A112H_set_bfr_H&type=h. I have tried several trouble shooting techniques, but I can't find it listed in my files or extensions, so that I can delete it. Also, I have Webroot, but when I do a scan, it doesn't show up. Thank you in advance for any assistance or information you can provide.

Regards, Marie Hatosky

I have Win 7 . I use the Fire Fox browser. Someone could go to my secure site and click the login box and retrieve all my user names. Why is this necessary to show these on a secure site?
