why does firefox blocks incoming http conection to localhost:8080 when I try to obtain a google oauth2 token using oauth2.py ?. The Google server returns the token via http to loaclhost:8080 and the port is blocked by firefox.

Dear Firefox Support Team,

I am encountering an issue where PDF files fail to display properly in Firefox, appearing as blank pages. This problem persists across multiple PDF documents, suggesting a potential browser compatibility or configuration issue.

   Adjust Firefox’s default PDF handling settings or implement necessary fixes to ensure proper PDF display.

Additional Details:

Why after the most recent update to version 139.0.4 64bit does any Google search result page on Firefox now use 110% cpu according to about:processes? This isn't the first time a Firefox update has caused this to happen on my computer either. It causes extreme system lag until I'm able to close the Google search result page in Firefox, then everything returns to operating normally. In the past subsequent Firefox updates have resolved the issue but it can sometimes be a while before the next update is released and that one is not always the one that fixes it. Is there something I can do resolve this without having to wait for future updates to be released?

How to fix this .

Why have ratings of reviews on Amazon disappeared and how do I restore that feature? I do not see a price tag in the upper righthand corner. I'm running Firefox on a PC w/Windows 10.

제목 그대로입니다.

절대로 테마가 아닌 새 탭 페이지 즉 아무 웹사이트도 접속하지 않은 상태에서 이미지 변경하는 방법입니다.

오늘 업데이트가 되었다며 이미지를 변경하라고 해서 아무 이미지를 넣었다가 되돌릴 방법이 없어서 1시간을 낭비했습니다.

절대로 테마아닙니다. 새 탭 페이지입니다. 어떠한 부가기능도 사용하지 않았습니다. 이러한 문제가 아닌지 검토하라는 답변을 줄 경우 무조건 최악의 평가를 내릴겁니다.

bold text I did something that made my FoxFire window cover 1/3 of the total window on my MacBook Air. It used to cover everything except the bottom and top bar. How do I get it back?

Until recently Ctrl+Tab and Shift+Ctrl+Tab have work perfectly. Now they do not work at all. Ctrl+Page Up (and Down) works fine.

I have used safe mode, rebooted the computer, checked the general settings in Firefox and the problem persists. What can be done to resolve this?

When I sign on to AOL, Mozilla suddenly starts sending pop-ups on the right side! I keep clicking them off but another appears a second later. I get the full block full of notifications numerically which I watch and click on the ones I am interested in. These pop-ups are SO annoying and I dont know how to get rid of them. I've been with mozilla/aol for over 20 years and now that I have a new computer with windows 11 - I'm stuck! Please help

As the title says, firefox keeps reenabling delete browser history when firefox closes on its own. After an update yesterday it seems to have reenabled it AGAIN. Back in May near the end of it it also reenabled itself and deleted years of firefox history out of nowhere and I never knew it did so until the next morning when I went to go to a specific part of a site I frequent only to find when typing out the keywords to it, didn't exist.

Found it reenabled itself on its own. Disabled that, and got some semblance of my history remembered again into the system. Made a backup copy of history to some degree into a copy of the places.sqlite file. Yesterday firefox updated again. Closed it last night when i shut off my PC to go to bed and this morning when I opened firefox, I find all my history is gone AGAIN. See delete history when firefox closes is reenabled once more on its own without my permission barely 3 weeks later. I then try to input the backup places.sqlite i made a few weeks ago as well and it gets overwritten by an empty one after I input it back in and open firefox.

I've tried searching for why and how this keeps happening. But every time you search anything on this topic its nothing BUT how to ENABLE the setting, nothing about it auto reenabling and how to stop it or what could be causing it. Web searches are legitimately 0% useful because its just nothing but one sided search results repeating the same thing ad nauseam.

Well, it is quite simple: you upgraded FireFox last night and now I lost all my bookmarks which is horrible and I really do not appreciate what happened and why? It never happened before.....

I am running Nightly 141.0a1 on macOS 15.5 When I two finger tap on a thumbnail image I see the first option is "open link in new tab" and when I choose it, it does as it says and opens a new tab, at the link, in the background. When I need to do this many times, to save a couple of taps, if I Command single finger tap on the thumbnail then on most sites that same thing happens. My problem is that on some sites this doesn't work. What I get is the link opens in the current tab and a new tab is opened in the background but it shows Unable to connect Firefox can’t establish a connection to the server at localhost.

Is this the particular site messing with Command click or is there a setting I can set that fixes this?

Thanks
