A replacement for Tab Progress Bar https://addons.mozilla.org/en-US/firefox/addon/tab-progress-bar/ which is not working on FF4 and upper versions. However I found some problems while interacting with other addons:
- It's causing problems with AdBlock Plus and Foxyproxy (at least), problems with both them addon/toolbar icons, with its items under Tools menu, and even with the window opening behavior blocking the opening of more than one window especially after session restore, also with ABP creating a useless bottom window sliding area overlapping webpage area.
- With Hide Caption Titlebar Plus https://addons.mozilla.org/en-US/firefox/addon/hide-caption-titlebar-plus-sma/ if I use the slimmed down tabs bar feature, and if I put the progress bars on tab bottom, the progress bars doesn't show. May this be happening with other addons/userstyles slimming down tabs bar.
- With userstyles (for Stylish) Combine Tab Icon and Tab Close Button http://userstyles.org/styles/43992/fx11-combine-tab-icon-and-tab-close-button and with Collapse favicon, progress indicator & closebutton http://userstyles.org/styles/66179/collapse-favicon-progress-indicator-closebutton this extension doesn't align correctly the progress bar if close button is risen, and causes the userstyles to work bad. Probably the same happens with the parent extensions of this one, Tab Progress Bar (so the problem probably is inherited) as you can read in my review of the userstyles of the above links.
Because of this, especially the first point above, I prefer to use Informational Tab for the progress bar on tabs, disabling all the features I don't need... that addon seems not to be causig any of the described issues, so it suggests this extension is not well constructed in the slimming down of Informational Tab (what it is essentially).
