Is there a way to protect a tab or window while uploading or downloading?

I am doing a lot of large-file uploading and more often than I care to admit I have accidentally closed the tab or backspaced the tab or clicked in the wrong place, breaking my upload. Then I have to begin the uploading process all over again: reloading the video, entering information and initiating an upload that takes a few hours. It's all very frustrating. Is there a way to protect the window? I know a lot of pages have a prompt that comes up asking if you're sure you really want to leave the page. This page doesn't. Is there a way to add this feature to certain pages? Or another way to protect a page?

I don't have any tricks to absolutely lock in a tab.

"Perma Tabs Mod" did a good job for most of that and changed the color of the tab. "app-tabs" built-in to Firefox was supposedly going to do all of that -- typically Mozilla never improves on what an extension does and generally only does a half baked attempt of replacing an add-on by building it in. Such as is the case of app-tabs except that there are some other advantages of "app-tabs" so it is better than a wash out. App-tabs does not change color but does change the size and I reduced the them smaller so you just have the icon without extra spacing and it does put all of the app-tabs to the left

  • Tabs Bar Minimal Size with a style change makes all tabs smaller and for app-tabs the consistent smaller size is further reduced so app-tabs always just show the favicon.

If you accidentally close a tab, use "Ctrl+Shift+T" or the history menu to restore it, usually you know immediately.

Protection against use of Back/Forward, don't have tricks to prevent that if it is in Tab Mix Plus that would hardly be a solution but beginning of more problems. Use the Back/Forward to correct in combination for watching out for the "color" change on those arrows.

Use of "app-tabs" will prevent you from opening a link to another domain from within the tab, it will not protect against at the location bar such as another url, use of the "AwesomeBar" internal search of history/bookmarks, bookmarks, keyword shortcuts (which are bookmarks). If you type something into the search bar or the location bar and realize you don't want it in the current tab you can use "Alt+Enter" instead of "Enter".

On sites such as this one you can use "Textarea Cache extension (32.8 KB) to recover the text area content. This site is very bad with regards to lost text area content with Back/Forward and other such things but the extension does a good job and even helps occasionally elsewhere besides (you get a lot of practice here, like several times a day). A little tricky to get used to but you need the button on the toolbar or addons bar (status bar) then use "Copy and close" or use the drop-down at the top for an earlier lost text area.

To protect a tab similar to "Perma Tabs Mod" where all links will open in another tab, you can install the "New Tab" bookmarklet, for which I give it a keyword shortcut of "NT:" for new tab.

I also suggest you install a tab counter and prevent tabs from scrolling off of the tabs bar.

Thanks for all the great information. There are definitely things there to help prevent accidents. I think the biggest problem is with the site and how easily uploads are reset. It would be great if there was a button you could press that would activate a warning prompt before the page changes or closes.

You can set the pref browser.download.manager.quitBehavior to 2 on the about:config page.
That will make Firefox ask for confirmation if you want to cancel the download if you close Firefox.

See:


To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

  • Use the Filter bar at to top of the about:config page to locate a preference more easily.
  • Preferences that have been modified show as bold (user set).
  • Preferences can be reset to the default via the right-click context menu if they are user set
  • Preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean)
