Firefox Support Forum

When I first started using firefox, I was using the restore tabs feature, so when I shut down my computer and reopened it I would find myself back where I started. With time I had a lot of tabs open across multiple windows. One day I lost these tabs when I opened my computer, I'll call these tabs set one.

I didn't use the restore feature, since I figured I would just restart and maybe manage my tabs, so I started fresh and start a new set of windows. This set obviously went the same way, lots of tabs over a few windows, that restore when I open firefox on my computer. This is set two.

But every so often now I'll turn on my computer and find that I am on a different set. My previous collection of open tabs is back and while I can see in my history what I have searched, there is no option to restore the previous set of windows. It's not often, maybe once every few weeks, but it will switch between the two sets of tabs.

It's annoying because I am working with these tabs so if I am back on a previous set, then I need to reorganize my windows. Anyone had this issue?

Hi... I did a Firefox refresh today. Prior to the refresh, my bookmarks were displayed of the left side of the browser page... now they are not. I can still see and access my bookmarks if I go into manage bookmarks. But, I can not figure out how to get them displayed as before. Would appreciate any help anyone can provide. Thank in advance.

Suddenly, now on FF 119.0.0.1, JPEG Images no longer open in new tab when clicked with mid-mouse-button (previous behaviour, wanted), instead they get downloaded, safed to DL-folder, and maybe opened in 3rd-party-app. I tried to change the Open-with settings, but to no avail - there's no option to 'Open in Firefox'/Internally. (Only Open with../Download)

I've tried older guides on the topic, which didn't apply here it seems, also cleaned cache, etc.

I updated from version 106 to version 118.0.2, then to 119.0.1. The last to updates made a local HTML page behave differently than before.

The problem is this: the "inside text" below was not(!) bold before the update, I suppose the containing element of the text defaulted to "initial," but began to default to "inherit" after the update.

This is HTML:

  <TABLE>
    <TR>
      <TD class="group">
        outside text
        <TABLE>
          <TR>
            <TD>
              inside text
            </TD>
          </TR>
        </TABLE>
      </TD>
    </TR>
  </TABLE>

This is external CSS linked to the page:

 TD.group
   { font-weight:bold;
   }

So I added "TD.group TABLE{font-weight:initial;}" to the CSS to make it work as expected/before.

I wonder why this change was made by the developers, Did I miss any changes made to HTML/CSS specification?

Thank you

I reinstalled Firefox, now 119.0.1 64bit on our Mac M2 now OS13.6 via download-reinstall in the owner account on our shared Mac. The "Firefox is being updated by another instance" line in About Firefox still has not gone away after closing and restarting Firefox.

Presuming this will disrupt future updates, I seek help.

Background: Last spring, I upgraded from a 2016 Mac on OS10.15 (which still appears on my Mozilla account) to this M2 OS12 now 13.6. I had previously set Firefox to prompt me for updates because they could disrupt my work on the old Mac. It worked fine up to 118 point something. Up to my ears recently in urgent other stuff, I deferred the prompt for 119. Then, frazzled, I just closed several 119 prompts. Today, after helping my wife use her account on the M2, I found in my Dock's active apps area an icon for something like Updater something-or-other. After a while, I swiped it away.

Only black screen. No any extension.. I tried clear cookies so many times.. allow all things website.. disabled.. none of these helped. Its same also on Chrome.. edge so yeah dont know what happened in one week because it worked last week fine only firefox and now not.. Tried ask here also because CBS support not want help me..

So I opened firefox today and it updated and after it updated my tabs are now like a 4th of my screen (see screenshot) and also the bookmark bar is now white where I believe it was grey or black before. I am not sure what to do to fix this issue.

Quick background: I live in the US. I wiped my computer while traveling in the Netherlands. I installed Firefox while in the Netherlands. I quickly noticed that the default language was Dutch. No biggie, I looked around and "managed language" to English in the Firefox settings.

The problem is that Firefox is still stuck on Dutch mode. Even the spell checker is stuck. Internal messaging is stuck (e.g. the messages on the bottom of the page while loading a site). I just went to DuckDuckGo and it defaulted the page to Dutch.

I understand that I could reinstall Firefox while I am at home (US). But I think this is a bug. The browser should be able to switch languages in the settings, etc.

Let me know if I am doing it wrong.

I get black and or white rectangles on web pages as I scroll or move the cursor. Some times they obscure what is on the page, sometimes a ghost of what is underneath shows through, sometimes they are like a layer between page components. I've attached a couple of screenshots to show some of the problems. I've reset Firefox but it made no difference. Any suggestions? Rhanks Tony

I'm using last release Firefox in a fresh install of Debian 12 with KDE. Trying to personalize colors and get a coherent style, I've installed Firefox Color and it worked fine, except for a few GUI elements.

I solved the scrollbars part with this answer:

https://support.mozilla.org/en-US/questions/1419353

Is there a similar setting for the menus? I mean in Firefox's menu bar or the ones popping over the page. The dropdown of the burguer menu and the bookmarks toolbar do get styled (I will include images showing the difference).

Thank you in advance and to zeroknight for sharing the bit about scrollbars!

Over the last five hours, I have gotten 27 emails from Firefox Monitor for this data breach, for the same email address. I have already marked the breach as resolved in Monitor but I keep getting emails. Is there anything I can do about it?

I am new to firefox, and not a developer. I have seen articles showing how to install a Language module (done, GB English), but when I right click in a text box all the advice says I should see a "Dictionary" sub menu, but I don't. Spellchecker works in Chrome and Safari, just not firefox. Any ideas...

.... when either trying to open them by clicking "open link in new tab" or by manually opening a new tab, then typing something into the browser-line.

This has been an issue for me now for several versions of firefox ever since like 6 Months ago. It is very annoying, especially after having finished typing a rather long website-adress or search phrase, then hitting enter only to get the new tab closed right into my face without any further comments.

Help would be >MUCH< appreciated!

Cheers~

With certain pdf files, when I go to a page using the outline feature on the pdf viewer or refresh the tab on the same page, the zoom will automatically be set to "page fit". It seems to happen with the title page and table of contents pages. Is there any way to prevent this from happening?

Is there a way to enable using both a default pattern as well as a custom image for the background on Firefox Color? I really want to enable both but it is making me choose one or the other. Please help me do this or enable the ability to do so.

About a month ago, I had no issues taking a screenshot of what's displayed or entire page. Now, whenever I take a screenshot, it copies only 3/5's of the page (from the left margin to roughly 3/5ths of the page both displayed or entire). My settings in about:config have not been changed (well, they are changed but at the same settings as when 'Take Screenshot' worked and now only copying 3/5ths of the page).

I have an account with a French language news site lemonde.fr and want to read the website in French. I selected this option, to default to the French language version, when I created the account on the site. However, Firefox redirects to the English version lemonde.fr/en. I do not want this and cannot figure out how to stop this from happening. Please provide specific instructions. Thank you!
