Is there a memory issue with Firefox in regards to how PDF files are shown?

This happens every so often.

When I open a PDF the font is distorted and it seems to be encrypted. I have to close Firefox and reopen and then the PDF file is displayed correctly without any issue.

Thanks.

bold text My FF web pages are way too wide and I have to scroll all the time from side to side, to see the whole page, back and forth! Hate it! Not workable. Not only that, the menu texts (not the fonts on the page) are way too small, unless I reduce the whole page with the limited percentage size, and then none of it is readable to me. For a while 67% size helped but not even that works right and I am CONSTANTLY trying to adjust things so I can see them! It used to work great and now it is a CONSTANT BATTLE TO FUNCTION!

I can't turn off lazy loading. I set the following about:config settings to "false":

browser.sessionstore.restore_on_demand browser.sessionstore.restore_tabs_lazily browser.sessionstore.restore_pinned_tabs_on_demand

Nothing changes. When I start Firefox, it simply won't load all tabs. How do I fix this?

I have a frequent problem with dead tabs in FF v121 on Win 10. I tend to have many tabs open (like 15 say) and it sometimes happens that a tab becomes completely unresponsive. It could be a new tab that I open or an existing one that I click on. When this happens I can't do anything. Page reload, clicking on links, entering an address by hand ... nothing happens. The tab is simply dead. The tab is essentially dead. After some time (usually 1-2 minutes) the problem resolves itself. However, it is very annoying as it happens almost every day and sometimes even several times a day. So I am looking for a way to solve, otherwise I will have to move to Brave or some other alternative. Any ideas what could be the problem? I also do not want to restart my browser several times a day as that logs me out of all websites I use including Whatsapp (I delete cookies when closing FF).

I got the v116.0 update yesterday and since then, there's been some annoying hiccups with loading webpages.

It's not a specific site that is having an issue and it seems completely random. The best I can say is that if I just do websearches from the default Duckduckgo engine or if I use !g to search google through it, eventually i'll hit the hiccup.

What seems to happen is that i'll try to go to the website/perform a search and then it will just load a blank white page and hang there. None of the browsing function buttons will be available (so can't click refresh) but if I highlight the address bar and hit enter again, it will suddenly load without issue.

Hello, I want open a private tab along side of an opened private tab . But every time it opens in an new window. So, i am shifting from chrome. In chrome when we try to open a link in private tab all the private tabs opens in the same window. So, I want to is this feature available in Firefox or not. If have how can I turn it on. Thanks.

Ever since I installed Firefox 123.0, when I execute a search on Yahoo.com, Firefox automatically opens up a new window or tab (depending upon how you have it set up in settings) when it didn't before. When I try this with Firefox using Google.com to search, it does NOT open up a new window/tab. But when I try it with Yahoo.com when using Google Chrome, it does NOT open up a new tab. So it would appear that the behavior is being caused by something in Firefox.

I tried making various changes in settings and Firefox about:config that were recommended in previous questions here, but they did not alter the behavior. I would like the behavior to return to simply performing the search within the same window (I can always scroll back to get the original page). Can anyone help?

I want to use discord in firefox instead of using the pc-program. It appears that my firefox.cfg has some preferences that block discord from gaining microphone access. I never used multiple firefox profiles but that changed now, i created a firefox profile for discord purpose only. However my firefox.cfg is active in both the default and the discord profile, again blocking microphone access.

As i said currently i use firefox.cfg and autoconfig.js to customize firefox preferences, but since this makes it impossible for me to use discord i will have to find another way to modify firefox, so the question is how can i use multiple firefox profiles with different preferences? Can this be done with a user.js file? After all what is the difference between using firefox.cfg and user.js?

I just noticed today that my New Tab Page is now displaying an old set of icons (are they called bookmarks?) It might be associated with the recent update to v121, but I have lost several newer pinned icons. The display today is shown in the attached image, and I have drawn a red diagonal through icons that have not appeared on my New Tab Page for some time. I don't have a list or image of the recent ones that are gone missing.

I'm sure I'll eventually find and replace the ones that I lost, but this is just embarrassing for FF, which I use for just about everything.

If there's a way to revert, I'd like to know.

I went into setting and made sure spellcheck is enabled and it is, but there are no other options there. I did exactly what it said on your help article and right clicked in the text box on multiple different web pages and there is NO OPTION. It should not be this complicated.

Greetings everyone,

Firefox is my preferred browser and I really prefer the Firefox Engine over Chromium that most other browsers use.

I want to install a backup browser that runs the Firefox Engine in case my Firefox browser has a problem.

I searched a lot and I thought installing this would be the best option: https://www.mozilla.org/en-US/firefox/developer/

However, I’m worried that installing the Firefox developer edition will change my Firefox installation…

I just tried to connect to YouTube & get "You're offline. Check your connection." I assume this is due to a DoH connection issue. I can connect in Chrome. My Firefox Mozilla Connection Settings are "Use system proxy settings", though I have set this to "No proxy" in an attempt to fix this - didn't help.

Under Privacy & Security: "Enable HTTPS-Only Mode in all windows", "Enable secure DNS using: Increased Protection" - tried "Default Protection" - no help. Using Cloudflare default.

It has been a few months since I tried YouTube - not sure what's up. It works in Firefox on my phone..

Hello,

The past few weeks I have run into the issue where Soundcloud fails to load and returns an error. This is circumvented multiple ways. Either I open soundcloud in incognito mode and it works fine, or I clear the cache in normal mode. BUT in the second option soundcloud only works during the first visit.

I found a previous question asked here detailing the same exact issue but nobody found a solution that worked. https://support.mozilla.org/en-US/questions/1346767

Other info I think would be useful: Soundcloud works on my laptop running the same exact profile for firefox. Hinting to me that something else on my computer is in the way.

Deleting all history, cookies, cache, extensions; has not helped

I have attached the images below just as the previous poster has. Including the console log filled with errors.

Hopefully someone can help with this headache!

Recently YT is barely loading videos with the message "if playback doesn't begin shortly, try restarting your device" or it simply stuck tried on edge and it doesn't happened can anybody help me diagnose this problem?

Restarting FF doesn't always work has to be done multiple times, and it soon breaks after browsing or restarting the browser

The grey bar on the player does load but the player never plays its just back

I suddenly can't click the "copy song link" item in Spotify anymore. It worked fine last week and works normally in Chrome.

It also fails in Troubleshoot Mode and after clearing Startup Cache.

I want to open online PDFs in Acrobat. I've modified the setting is in Firefox to "Always ask," yet when I click on a PDF it opens as it should AND Firefox automatically downloads the file to the Downloads folder even though that destination is greyed out in settings and the radial button for "Always Ask" is selected. How can I block this activity in either Firefox or in the registry.

NOTE: ALL OF THE SETTINGS IN FIREFOX SAY "ALWAYS ASK." This a software bug in Firefox, not a user switch setting. This activity began today (March 11, 2022) after months of normal, expected activity. I've reset Firefox and I've done a complete uninstall and clean install and this still happens.

On my video gallery page, some of my videos are stand alone and others are a series of two or more videos. When you click on the series, it takes you to the page where all the ones in the series are housed, but then when you click on one of the videos in that series, I receive a prompt from FIREFOX: Receiving prompt on my created web site "FIREFOX CAN'T OPEN THIS PAGE" Open site in new window...

This totally messes up my ease of use for customers and is keeping them from following through. I would like this feature disabled if possible. Any work around for this?

Thank you for any help and consideration! -Carol Ragsdale ([email]@msn.com) www.westmarionbaptistchurch.com
