Firefox Support Forum

I am not a computer geek and I think I want a simple thing: when I start Mozilla Firefox I want zoom level to be set automatically at 150%. In another words I want Mozilla Firefox to remember that my preference is 150% zoom level so I do not have to retune it each time I start Mozilla Firefox or open new tab. Is it possible? Thank you, Mike

On Windows 10 Latest Update.

Firefox is all white and blank. I can guess where the interface is and I restart in safe mode with add-ons disabled. When in Safe Mode it appears as normal. I checked my add-ons and removed them but it didn't help.

I tried a complete uninstall of Firefox>restart of my computer>reinstall and no change.

Hi.

• I have disabled addons one by one until i dont have any, still problem.
• Tried a fresh profile
• Tried updating the graphics drivers
• Made sure Flash and other plugins are up to date.
• Tried updating to the beta
• Tried with and without electrolysis enabled.

Chrome works fine.

The image is of Youtube when this happens.

So the thing is,the entire page is flashing black,as you can see in the screenshot.And when it's black if i hit f11 or i change the tab and go right back ,it fixes but i can't see things like the home button in facebook for example.Or the chat in facebook(it is completely transparent, i can only see the text and can't see any emotes,it's frustrating.) I tried the following: -Reinstall Firefox. (same) -Switch to Chrome. (same) -Switch back to Firefox and reinstall my graphics drivers and updating flash player. (same) I have to admit though,before doing all that i was getting this on every website,scrolling down for 10 seconds and this happened.But now it's mostly happening on Facebook,not so much on other websites.But in particularly,facebook is impossible.I can't even watch a video without the entire screen turning black and only the video being shown. I'm really out of ideas,could need some help.

I have 2 monitors:A and B My setup: work on monitor A (primary one), put firefox browser on monitor B. What I need: I need to play fullscreen on twitch.tv/youtube/... on monitor B (it always go fullscreen on A whenever I try, even though I putted firefox on B)

Why the default fonts are looking so ugly? It is working fine on Edge. I am on Windows 10.

After restoring windows 10 and reinstalling Firefox all my script is blurred, not sharp characters as before.All web pages,everything including this page. Have tried everything I can think of, hardware accelerator, etc. Help please. Thank you, Mike

Since updating to Firefox 40.0 (in OS X 10.9.5) browser windows and the toolbar show strange black lines and squares when the window is resized. Websites are messed up with black backgrounds or disappear beneath a black layer. The toolbar often disappears too, except for the three Mac resize buttons. It renders Firefox completely unusable.

It’s similar to what is described here: https://support.mozilla.org/nl/questions/1071126 and the bug described here: https://bugzilla.mozilla.org/show_bug.cgi?id=1032769

None of the offered solutions or workarounds seems to help. Disabling all add-ons and extensions doesn’t help either. I only use the Default theme.

Solution To my own surprise the issue disappeared completely when I installed and started to use another theme (Simple White)…

So it seems that Firefox’s Default theme has a serious bug?

Hello.

I'm trying to figure out why Firefox won't scale my svg image (the logo) properly. Here's the website. It works in Safari, Chrome and, with added CSS, even in IE. So what's the deal, why won't it scale in Firefox?

Thanks! Fredrik

hello,

since today I notice that all text in firefox (56.0 mac-version) on certain sites appears only in question marks (in suqares). looks like that on sites like mozilla support (busy right now in safari) google.com, my banking site, tmobile, gmail and a lot other ones too. all those sites show totally normal in other brouwsers.

did the following troubleshoot 1) view > text encoding > unicode = OK 2) preferences Font & Color > advanced > checked 'allow pages to choose their own font' = OK

any other suggestions? (:

tried to enclose some screenshots (small jpg and png files) but the upload keeps spinning for ever... never mind.

thanks in advance for any help on the questionmark problem.

For some reason the theater mode it no longer (as of today) working properly. It does turn the upper part of the screen black as it used to, but now the video itself is very tiny within the black area. Also the black area itself is smaller (top to bottom) than it used to be. I don't know if this is a problem with youtube or a function of Firefox. Note that I did upgrade to windows 10 just today as well. Are there settings in firefox that will fix this or is it truly a youtube problem?

The video in the theater mode is actually smaller than the default mode. I have included a pic of both default and theater mode

Hi. I could always see the thumbnails of the magazines on the webpage dowmmagaz.com where you can download them in PDF format. But I had to reload Windows as I got a new motherboard. Now suddenly I cannot see the thumbnails on this specific site anymore. What can I do about this? What settings prevent the thumbnails to load on this webpage homepage? I can see the magazines image as soon as I click on it. But cannot view the homepage images

Thanks

I have a problem with the menu drop down. When I click on it, it is cover with black color, sometimes the whole drop down, sometime with pixelated borders. When the cursor moved to the black area, it disappears and the text show up. It happened some times ago but only on occasion. Started yesterday, I noticed that the black color occurs every time I click a menu drop down.

I tried the solutions from the following question, but it did not work.

It only happens when I use Mozilla, no issue with any other browsers. I have a Dell Inspiron 13 - 7000 series.

New Firefox user. Frequently I visit text only page- data strings are quite long. The default view for text only appears to be "Wrap Long Lines", which defeats the sorted information by line. Fortunately I found Page Style under View when I turned on Menu Bar. But when I revisit or refresh the page it defaults back to the word wrap, its getting old. Is there a way to change the default to "Basic page style"..or turn off word wrap, permanently. I looked under options but just havent seen a way to change this. Thanks

My operating system is Windows XP. After the last upgrade to Firefox 29.0, web pages began showing nbsp; through out including my home page. I never saw these until the latest upgrade. Internet searches indicate this indicates a space when the web page is developed but is not intended to be displayed. Why am I now seeing this on most web pages I visit? Is there a change or fix I can install to prohibit this from being displayed? Thanks

I am in Linux Mint and I am using a TV with a HDMI cable, my tv is my second monitor, but when I click something in my first monitor the video automatically exits the fullscreen, can somebody help me?
