Firefox Community Forum

Hi, I want to use dark background color theme in the Mozilla Firefox PDF viewer, read here https://support.mozilla.org/en-US/questions/1434510 but cannot find "userContent.css". My question is where can I find this file on a Windows 7 or Windows 10 installation?

Firefox is adding empty lines to the css file in web developer like so:

1. videoFiles {

 left: 0;
 z-index: 3;
 width: 250px;
 height: 40px;
 opacity: 0;
 cursor: pointer;

}

1. image_files {

 height: 40px;
 width: 250px;
 z-index: 3;
 opacity: 0;
 cursor: pointer;

}

.previewVid {

 width: 50%;
 padding: 10px;

}

Those empty lines are not in the css file and so it is reporting the wrong line numbers. So hard to find the correct line in the actual file.

Hello - I've noticed lately that when I type a search, sometimes Firefox does nothing. It doesn't pull any results, it acts like I've done nothing, but I can see the search terms I typed in the address bar, separated by + symbols. It simply doesn't go anywhere and doesn't perform the search. I do a lot of searching when I'm working and this happens approximately 1 out of every 15-20 searches. I've attached an image where I opened a new tab, typed my search term and it remains on the homepage. You can see the search terms in the address bar.

Up until a few weeks ago, I could see and access Mobile Bookmarks (I sync these to my Firefox Desktop) using the Firefox Desktop browser from the Bookmarks drop-down menu in the topmost toolbar.

Now, I can no longer find Mobile Bookmarks in the Bookmarks drop-down menu.

I can still find it by choosing Manage Bookmarks and, in the resulting pop-up, I can see it in its regular location there. However, this is significantly less convenient as it requires me to juggle another window and perform more clicks.

Is it missing due to a bug? Does Mozilla intend to fix/address this?

Thank you in advance for any help.

On using Google search, many times it behaves as if I've done nothing...

Communication between Firefox and their server seems dropped. Press enter/search and... nothing

Or do they* want us to use Chrome?

Seemingly straightforward searches through the options like:

• "Reset firefox"
• "Clear cookies"
• "Empty cache"

None of these things pull up any results when searching the settings... Why?

Firefox keeps getting "An error occurred during a connection to redirectlinkway.top. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR" when I try to use Juno email.

Microsoft Edge works fine on Juno email, but I don't and to drop Firefox in favor of Edge. Firefox has all of my bookmarks and all of my passwords.

I want to link my Firefox Account between my iPhone X Device and my Dell Laptop. I need to know how to do that in detail.

Note: I tried opening the menu and clicking sync and save, but I couldn’t see it on the menu, the same thing happened when I looked, as advised, when looking for Ready to scan; I couldn’t see it on the menu !

Kindly explain what should I do in clear step by step detail, as pertaining to these two devices which I am trying to link.

Thanks and my regards.

I am looking into an issue for someone that is using private browsing and to use a financial app. He has the website in the exception list for pop-ups but every time he opens this app in private browsing it asks for him to allow pop ups. When he added the exception he was in non private browsing mode.

My question is, even with the link to this site added to the exception list, is it completely normal for pop-ups to be blocked every time you open private browsing to the same website?

When I copy something to my clipboard I can paste it into Firefox. Into web pages and also into the URL bar.

But when I copy something in Firefox, it does not go to the clipboard. The clipboard still hast the content which was already there.

Also strange: When I cut text in a textarea, input element or the URL bar, the text is removed. But it is not sent to the clipboard. When I cut and paste, the text I get is what was previously in the clipboard.

What could be the cause? How can I debug this problem?

I accidentally closed Firefox with about 100 tabs open (doing research). I still had one ff window open with only one tab and I went to History (there is no session restore on my firefox-been thru that before) and selected restore recent tabs. That only opened about 10 tabs . BUT, now that becomes my " previous session" so how do I get my earlier session back. If I close FF and then open, all I get is that window with 10 useless tabs. This has happened before so I have FF set as default, and "open to previous window/tabs is selected". So how do I get my previous session open?

Starting today, amazon web pages are not updating correctly. The amazon web page appears normal till I sign in, then it doesn't update "cart" contents or show account holders name or list any "Lists" when accessing account saved lists. I have deleted entire history, and all cookies and caches X 3. I Rebooted computer along with a "system command control reset" and still the pages are not loading correctly. Short of reinstalling "Firefox" what more can I do? Are there any "Preference" files or files with specific extensions I can delete? Thank you. Gerard

I have gone to sites that already have my stored password. The saved password is not populating. I deleted the password. When I go back to the same site, it did not ask to save my password even though the option is selected is settings. This started after the recent update.

When I go to History and then Clear Recent History with History and Temporary File checked and the hit Clear nothing happens.

I found that I can delete the histories one by one with the Delete key.

Browser is not letting me choose the airports on Breeze Airways. No issues with using Safari. Also, American Airlines is sometimes spotty using FF, not loading the main page.

Today, it started.

When I open sites that I am subscribed to, a small gray-shaded nearly transparent rectangular window appears in the upper right of the screen (see attached screen capture), and it blocks access to login and search, thus rendering the site inoperable. The latest site rendered inoperable is Amazon shopping, so this is not a minor thing. I can no longer retain Firefox as my default browser.

No other browser on my Mac does this; the earlier version of Firefox active last night did not do so either. What is the purpose of this gray-shaded window? It makes the latest browser appear to be infected with malware.
