Firefox 技術支援討論區

Hello,

It's been a while since the release date of chromecast on browsers.. Today, year 2020, all the chromium based browsers add chromecast (Edge, brave, chrome, etc..). My favorite browser is firefox, and i am forced to use a chromium based browser to cast to my androidTV's. Sometimes i think to leave this browser and use a chromium based all the time.

I searched and installed chromecast extension to firefox and nothing works to me, and they are not user frindly as chromecast extension on chrome.

Can you tell me if you even think in add a chromecast extension in firefox by default?

Thanks,

Fabio BISPO

Any clue why the add-ons like Adblocker and frankly all the others no longer show on the toolbar? Makes them useless when the icons are missing. Anyone have the answer? I've refreshed. I've re-installed. I've stood on my head - nothing seems to help!

Using Firefox and accessing my gmail account. A notice comes up saying "A pop up blocker may be preventing the application from printing the page. If you have a popup blocker, try disabling it to open the window". I have no idea how to find what this pop up blocker is so I can disable it.

I cannot get Firefox to go completely into full screen on Mac OS Catalina. When going full screen it will hide the Mac system menu bar at the top, but it will not hide the Firefox address bar. I've researched a bit and found some suggestions about settings in about:config pertaining to full screen access, and I've exhausted all of those suggestions. Is this a known issue on Mac with Firefox?

I am building a website and, for the last couple of days, when I make changes to the CSS file they are no longer being picked up by the browser by which I mean they aren't displayed in the web page nor in the developer tools inspector.

They are visible in Chromium browser and dev tools.

I have cleared the cache and refreshed the page to no avail. It is only when I restart the browser that the new style rules take effect in the browser and show up in the dev tools.

A recent Firefox update has totally disrupted our ability to print from browser windows. There used to be a "Print Preview" button that allowed us to set things up the way we wanted them. That's now missing. As a result, stuff that used to cost us for ten pages now costs us for twenty pages. Also, when we print double-sided, the second side prints upside down.

This strikes me and my wife as a horrible development, and we would like to go back to the old version ASAP!

I 'refreshed' firefox as suggested. The guidance suggested that all my logins and passwords would be preserved but when I check the Logins and Passwords all have been cleared. I am now faced with the arduous task of resetting many many login credential. Poor advice from Mozilla.

While playing one of those free poker games there seems to be excessive RAM memory usage. Nothing else running which can account for it. Also, it shows several Firefox processes while, again, there's only one tab open.

The reason I noticed is that the game which usually runs smoothly began to be choppy/jerky, so I opened Task Manager to have a look. Note: Didn't investigate internet connection speed.

Why is Firefox using so much memory and slowing things down?

I am in Windows 7, 64-bit. All of a sudden all of my Firefox logins and passwords are missing. I read several threads about this, which told me to check the "Old Firefox Data" folder on my desktop for the logins.json file. However, the only information in that folder is from 2018, two full years ago. Where did my logins and passwords from yesterday go?

Also, I just updated to version 80.0.1, hoping to get my passwords and logins back, but they are sill missing. The problem just occurred today, before I updated from version 79-something.

Thank you for any help you can give. This is extremely upsetting.

I need to know when a visitor to my site is clicking the back or forward button. The reason is I have a "tabstrip" that hilites the currently selected tab and the target document is displayed in an iframe. If I click the back or forward buttons the page is updated with the last or next document in the iframe, but the tabstrip is not updated to reflect the change. Part of this is due to me not knowing how to update the tabstrip, but also because I don't know how to detect the back or forward buttons being clicked.

So I need to know how to detect those button clicks. Also, in researching this, I noticed that there seems to be an idea that you can't distinguish between the forward and back button, only that a button was clicked. That doesn't make sense given that each button has a specific action that is opposite of the other. I need to know the truth about this.

Finally, as much as I use only Firefox myself, I know there will be others who use other browsers. Is there any difference between detecting the back and forward buttons on other browsers compared to Firefox?

One of the pages I need this for is here

Edit 15 March 2022:

I had to fix the link because I had renamed the page when I finished the work on its layout. Also, since I asked this question I have realized another similar and sort-of related issue on a different page: https://wayneca.neocities.org/WebDesi.../TagList.html. The relation is that the back and forward buttons don't correctly reload the page. The difference is that this one is concerning named links.

When you click a link in the table on the left it correctly moves the document in the right table to the point where the matching id anchor is. But when you click the back or forward button the tables do not shift back to where they were on the page as reloaded. The back and forward buttons work fine if the link anchors and id anchors are not in tables.

I have been told about the history functions, but I have found no examples of using it to correct the issue in either of the above cases. Is someone here able to point me to examples of using the history to make a selected link reset back to where it was or reload a page with the last jump point being reset correctly?

Also, why does the named link thing work without tables but not with tables?

Hello!

I used to be able to open a file (with a program) without it being saved. Ever since 98.0, the "open" option saves the file regardless. I even had to find a work around to get the "What should Firefox do with this file?" prompt.

Is this no longer possible?

Thanks.

I can't download my files from https://drive.google.com/drive/my-drive. It started after upgrading Firefox.

over the last few days there is a small vertical cursor line that appears at the last mouse click location like it's waiting for me to type something there. like the browse button below. if i click outside the box a blinking vertical cursor line appears outside the box where i clicked. it is obviously not a place where input should be expected. this has only started over the last week or so and only with firefox it doesn't happen with chrome. I just opened a story on fox. the title of the story is not a link or a place for me to type or enter text but if i click anywhere in the title text a blinking cursor line appears.

I have a folder on my desk top that reads "Old Firefox Data". This popped up when a newer version was installed. How can this be imported back into my newer 80.+ version? I have lost most history, bookmars, etc.

Firefox did an update to their 89.0 version and now I can't log into any Google accounts (or any emails at all) using the Firefox browser. The reset button on my browser will quickly flicker once and nothing else happens. When I use other browsers, I am able to get into my Google accounts and other email systems that are not Firefox/gmail.

No matter which website PayPal is used on, as long as I try to pay from Firefox, PayPal will not load the payment screen. Other browsers perform the sane transaction just fine. I have tried clearing cookies and cache. Also, I have tried the security icon in the address bar. Why is this happening?
