When I download PDFs on my MacBook using Firefox (currently 124.0.2 (64-bit)), they are always blank - I have attached a screen shot.

But if I download the same PDF using Safari, it opens straightaway - 2nd screen shot.

Is there something I need to adjust in Firefox to allow PDFs to open?

How can I find or add the translate icon to the toolbar. I did a screenshot but can't see how to insert it. My tool bar has only a toggle reader icon and a favorites icon after the url in the address bar. translate does seem to work automatically on the first page of website, but then does not work on other tabs of the same website. screen shot added

Twice in the past 2-3 weeks I have had to restart the computer, Linux Mint 21.2 Firefox 124(when updated in the past couple of days), due to the mouse freezing up and not being able to move the mouse on the screen. That's not the current problem, but it might help direct things to the final solution.

After the most recent reboot last night now I'm having a rather problem. The up/down arrow keys are no longer scroll me up and down a webpage like they always have in the past. Instead of doing smooth scrolling like they always use to, now they are scrolling me up and down the links on a web page. For example, if I were to be on youtube it would first want to scroll me down the left side links before taking me through each and every video link, when the page goes to load in more videos than it wants to go back and scroll me down the left side links again. It acts like it is taking me through the html code, line by line, instead of scrolling me smoothly down the webpage. The only way I can scroll smoothly down the webpage is to use the mouse on the scrollbar on the right side. It does this both in normal mode and in Troubleshooting Mode.

I have checked and beret scrolling is false as well as beret_shortcut. Use autoscrolling, use smooth scrolling, show scrollbars and always underline links are all clicked on. Always use the cursor keys to navigate within pages is unclicked. I have tried different changes between clicking on and unclicking those options with no change being noticed.

How can I get this back to the way it used to run?

I accidentally pressed a lot of keys on my keyboard and for some reason the default colors of Firefox have changed. I found out that by using Ctrl+Alt+D that I can switch the colors back to normal or to the colors that now appear automatically, but this only works for one tab. If I open a new tab, it shows the weird colors (see images below). I tried looking up specific shortcuts for Firefox considering the shortcut mentioned before (Ctrl+Alt+D) only works on Firefox. But I can't find any shortcut tied to that combination. I'm unsure what to do and how to fix this.

I would appreciate it if someone could tell me how to fix this.

I made a small CSS customization to my tabs in FF 115 ESR on Windows 7, so they would be flat on the bottom and rounded on the top, looking a bit more like tabs instead of buttons.

Looked ok in FF 115 ESR.

However, in FF 125, half the tabs are now cut off, including their text (see attached images).

Also the tabs background is darker in FF 115 ESR, providing more contrast between the tabs and the tab bar. In FF 125, it's almost all white and I can hardly distinguish between the tabs and the tab bar.

Why is there such a big difference in appearance between FF 115 ESR on Windows 7, and FF 125 on Windows 10?

Here is the code I used...

/* ------------------ RESIZE TAB BAR ----------------------------- */ \#TabsToolbar { height: 27px !important; margin-top: -1px !important; margin-bottom: 0px !important; } \#tabbrowser-tabs { height:25px!important; min-height:25px!important; }

.tab-background-start[selected=true]::after, .tab-background-start[selected=true]::before, .tab-background-start, .tab-background-end, .tab-background-end[selected=true]::after, .tab-background-end[selected=true]::before {

 min-height:25px!important;

.tabbrowser-tab {
 max-height: 25px !important;
 border-color: #8f939e;

 max-height: 25px !important;
 border-color: #8f939e;

} /* ------------------ TAB HEIGHT END ----------------------------- */

I inserted backslashes at the beginning of the first 2 lines of code above to preserve the hashtag sign (otherwise it displays an index number before those lines), please ignore the backslashes.

I would like my customizations in Firefox 125 to look like the ones I made in 115 ESR.

Is it possible?

Thanks!

I have language set to English (GB) but am being constantly annoyed with words like "colour" being underlined as badly spelt. Why aren't you using an English (GB) dictionary?

Many, many websites now have this behavior: at the top of an article or blog post is an embedded video. (Or sometimes, partway through.) Scrolling past the video causes it to jump to a sticky position in the lower right corner of the window. (See attached screenshot.) Also, even if various disable-autoplay boxes are ticked in my settings, the shifted video will always start playing.

Granted, most sites provide a little "X" to close the video. At worst, there is the pause option. But still, it's an annoyance to have to do this on soooo many sites, every time I visit to read something.

Key word there: read.

My point is: if I wanted to watch the video, I would have, when it was right there in front of me. Since I have scrolled past it, this ought to be an indication that I do not want to watch the video.

So, the request is some sort of option in Settings that would prevent this behavior. Enabling it would do nothing else to the page except prevent the behavior as described.

Thanks for listening!

When visiting the "support.mozilla.org site, third-party translantion add-ons(such as "Immersive Translate") can't work. It says "can not read or change data on this site". I want to translate it on the same page rather than skipping into a new page. However, it can work on the "www.mozilla.org" site. When visiting on Chrome, there is not a problem. Is that site just privileged on Firefox ?

All downloads I make inside of Firefox are automatically failing, with "Failed" message. This only happens in Firefox, Microsoft Edge downloads are perfectly fine. I've tried starting in troubleshoot mode, disabling anti-virus, clearing cache and downloads, rebooting PC.

Some recent changes in PC include: changing TEMP and TMP system variables to another drive (I've changed them back to C drive, had no effect) and making C drive a dynamic disk. Yesterday downloads were working fine. Thanks in advance.

This randomly happened over the past few months but last couple days it's bad. The Google Sheets cells I have open on Firefox turn black. You can scroll and they will come back but just briefly and back to black. Very annoying as these are shared sheets for my business with other employees. It's not happening in Vivaldi Browser or Edge. I hate Chrome so not even trying it there but guessing it's fine. Seems to just be Firefox all of a sudden. See pic. Help please as I have no clue what's causing this.

Hi,

Why is it so much updates all the time with Mozilla Firefox NIGHTLY Browser for the 127.0a1 version that was released 15th of April 2024? I don't even see the benefits of the updates or any information and what the content is in them. by clicking on "What new" doesn't show anything other than this from 15th of April.

When I open a new tab, I can't automatically start searching anymore.

Here's a video: https://www.loom.com/share/ebcc8685187a4e2284cf40b75f7e134e?sid=9b0a3db3-fcac-4bae-9ff9-cdbe2b8b955b

Now, I have to click into the search bar to type. That's annoying.

Anyone know how to fix this?

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

Hi. i have no results while doing this: https://dpaste.com/FTXPQ46ZL# No error, no screenshot. "Screenshot" flags in default state, about:policies - inactive.

Sync just does NOT work. I installed FF on my Mac brand new and fresh... brand new machine. Signed into Sync. NOTHING. After 6-7 HOURS... nothing. It just gets NOTHING AT ALL from my Windows Desktop.

I've signed out of ALL Firefox/Mozilla sync sessions... signed in clean- all browsers are up to date. And the about:sync-log page shows a LONG streak of errors... NON STOP ERRORS.

Why?! Why can't we just sync extensions to install and bookmarks across machines? How is this that hard for Mozilla?!

Day after day and attempt after attempt of failures for a basic function of the browser.

Here is the text of the latest log and showing constant connection errors- mind you NOTHING is breaking on my internet as I'm often streaming things and watching stuff while surfing, or others in the house are. Our connection, and Firefox getting online, are all working fine. I am at a loss. I don't understand how this is so terribly broken out of the box that you can't just sign in and let it talk to their servers. I know Google has billions behind Chrome, but this shouldn't be so 1990's bad by comparison to Chrome sync.

Using Linux Mint, Firefox 125.0.2

I'd like to be able to open a link in private mode by holding down some modifier key, then clicking on the link. There are many times that I want to open a link in private mode, and a keypress + click would be the quickest way to do it given that one hand typically remains at the keyboard while I use the mouse/trackpad.

I've even added a toolbar button to open a new private browsing window, then dragged and dropped a link onto the button, but that gets a circle with slash icon and nothing more.

Others have asked this question, so, to be clear, none of the following address my question: copying the link then opening the private browsing window & pasting the link, using a customized shortcut/bookmark, opening Firefox in private mode via command line, right-clicking the link then selecting "Open link in new private window".

Thanks for any advice and thank you, Mozilla, for Firefox!

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

Just updated a friend's computer from Windows 7 to 10. Installed firefox over previous ESR and now there's no way to remove the search bar from the new tab page. On my W10 system, the search bar isn't there, not sure how or why, but on her's there's no option NOT to show it as there used to be.

I found some VERY old (2014) info on this but doesn't seem to be up to date.

PLEASE give us our options back and stop taking them away, sheesh, getting as bad as Microsoft.

Is there a workaround for this to remove the redundant search bar from the new tab page since you can search from the address bar?

Thanks!
