  • This deserves 10 stars!!! I tried all screenshot extensions but Screengrab is the best one so far.

  • Great addon, thanks a lot!
    One thing I can ask for is auto selection of frames under mouse for Selection regime (like adblockers do to select unwanted frames). This would simplify the process of selection and, if needed after auto selection, user can edit the borders of selection.

  • thank you

  • Don't work properly.

  • Automatically [by default] posts your screen capture for the world to steal !! Capture all of your sensitive data and your bank records and share your account with the world. Until the developer sets the default post to [NO ONE] this app is a serious security risk. I don't want to share any of my captures, I want them to remain locally ... ON MY HARD DRIVE ONLY BY DEFAULT!!

    Oleksandr, do everyone a favor and change the way you have that setting by default, I don't trust your responses you post here claiming that screen captures remain locally hard-drive when your settings claim by default they are being shared to anyone that wants them.

    JUST CHANGE IT to the right way, just do it.

    It is not true!
    Please provide your proof by examining the code of my addon!

  • I love this add on. I probably use it more than any other. I do want to say tho that if it goes to having ads, if they're very intrusive, I'll delete it. I am making a $ donation and I would rather pay for the add on than have ads although I do understand the need for income. But.. I do love love love this add on and am on my way to send $ to the developer.

  • It grabs whole site without breaks between screens where they get glued together, as seen in some other addons for screengrabbing whole sites. Thank you.

  • A handy app, but the newer versions (compatible with latest version of FF) does not remember the last location you saved an screenshot - so everytime you save you have to re-navigate back through the file structure to place you want to save (unless you want *everything* dumped into a single folder).

  • Works perfectly, and highly customizable. Best in class!

  • Version 0.99.12 is still the way to go. Too many troubles for the new versions.

    Because of WebExtensions, I halted my classical Firefox updates to Quantum version for months. Until recently, I opted to update to FF Quantum. Very soon, I realized there are still many shortcomings with the new Screengrab. I will name a few:

    • The older version has two buttons, which are way handier than one. There are situations where I only take a screengrab of Visible Portion, and where Complete Page (for file size reasons). Using Hotkeys conflicts with other programs' keybindings. Now the new version only allows me to click 1 button for full screen. What if I want to take a portion of a screen? I am forced to use hotkeys --- not good. I will then reroute my keybindings with other programs. Yuck!

    • This new Screengrab is not efficient on a 4K monitor or Mac Retina Display. What do I mean by this? In previous version, Screengrab take the entire page at the right file/image size, either when I am on a 32" 4K monitor or a 24" 94.3 PPI monitor. The screengrab processing is very fast and efficient. Version 0.99.12 has no file/image size issues on a 4K monitor's native and HiDPI mode. It just works flawlessly.

    With the new version, it is a different story. In a 32" 4K monitor's HiDPI mode, the new Screengrab will take the entire snapshot based on how many pixels the monitor has. The more pixels you have, the larger the file/image size it will be. This has several drawbacks: Screengrab now finishes the processing at least 6~10 seconds slower for the entire page, sometimes not even working. For instance, the PNG file size could blow up from 2MB to around 30MB, which is about 10~15 times larger! The PNG image size becomes way too big when taken in HiDPI mode. For the 4K native mode, the file/image size is about right as Version 0.99.12 but then everything is too small to read (a 4K user would know what I mean by this). So most 4K users use HiDPI mode instead of 4K native mode. This essentially makes Screengrab impractical to use.

    The developers do provide a slide bar (for JPEG only) to let users adjust screengrab image quality based on the monitor's PPI. The idea is good but then has another disadvantage. The slide bar is for JPEG only. It is designed to change image quality, not image size. A 1% quality JPEG screengrab on a 4K monitor (HiDPI mode) will still be shown as super sized image. This is not practical at all.

    An ideal solution is to bring back the original Version 0.99.12 image size configuration, making the file size independent of monitor's PPI, native, and/or HiDPI modes.

    Why so?

    Many users switch to a Retina laptop while working in the office, and switch to a desktop display at home. Fixing a screengrab file/image size percentage means I have to manually adjust screengrab file/image size once when I am in the office. When I work on a desktop monitor at home, I will have to manually adjust Screengrab settings for a different monitor again. This becomes super inconvenient because I will have to manually switch screengrab file/image size settings every day if I work on different sized monitors! Sometimes, end users may forget to do the setting switch.

    So to rid all the troubles, just bring back the original Version 0.99.12 file/image size configuration. The image size is simply right no matter which monitors I am using --- a 4K monitor, a laptop Retina display, or a Dell U2412M. The file size is not too big, very efficient for disk storage. The image size is also not blown up if the PNG screengrab is taken in a 4K monitor's HiDPI mode.

  • Toolbar icon context menu problem.

    When I disable main context menu in settings,
    toolbar icon right click context screengab menu item is disabled too.
    please show it always regardless of settings.

    Developer response

    thank you for your suggestion!

  • Does not function. I can't set or find the folder that it supposedly save screen shots to. Even after finding a folder with the name ScreenGrab.

  • Eu uso scrrengrab a mais de 10 anos! The best ever!

  • Full of options, most notably the possibility to save the full page (including the part outside of the screen).

  • Once again: Screengrab WAS perfect, new version sucks.

    In "save as" dialogue, PLEASE point to "last used" folder by default, NOT to the default download folder.
    You may keep the option to a special download folder, but do NOT force pointing to the one and only same folder. It's ok to use the defaults as starting point at first use, but NOT eternally.
    Point to "last used" folder whenever screengrab is used more than once per session.

    Sorry, but these are the limitations of WebExtensions

  • fr

  • One of the BEST and most useful add-ons! Thanks allot for this.

  • it has great options and it never fails...

  • This extension simply does not work. Or if it does, it is far too complicated to figure out how. Give me two simple options: save full page or save selected portion. This would appear to offer those options and many others, but no matter which option I try, it doesn't work. After multiple attempts, I deleted it.

  • Diese Erweiterung benutze ich seit Jahren, um aus einer ganzen Seite bequem ein screenshot zu machen. Danke an den Entwickler und meine begeisterte Empfehlung an jedem, der schnell und bequem ein screenshot aus dem sichtbaren Hinhalt des Fenster oder aus der ganzen Seite (also auch inklusiv dem noch versteckten Fenster-Bereich) machen will.

  • I just discovered that by default the "Disable Upload" checkbox is NOT checked and that by default under the Storage section " +" is selected. I don't know if this means everything I have grabbed has been uploaded to those two sites but if so that is a MAJOR security issue!!!!! I think Firefox should ban this extension until either the ability to upload screenshots is removed OR they make it so that the default is NOT to upload anything and you have to take affirmative action in order to upload. Even if this doesn't mean that screenshots are uploaded by default unless some other action is taken (although I fail to see what action you could possibly take that would cause an upload to happen in that case), that "Disable Upload" checkbox should ALWAYS ALWAYS ALWAYS be checked by default, otherwise people will be freaking out like I am right now. It doesn't help that if you actually try to go to to see what is there you get a Russian language site!

    Developer response

    The presence of the upload function does not mean that all your screenshots have been uploaded somewhere without your permission.
    User, and only the user, decides what to do: copy the image, save the image to disk or upload the image to the Internet.

  • 很好用,做视频,很适合

  • Excellent! There is a "Fast mode" option that allows you to bind the button to a one-click function. I use Copy and Selected area. Fast, easy and effective. Many thanks.

  • When you do a "Complete page (Force Mode)" Capture, from a long-scrolling webpage,
    the results are Not good at all.
    Some images and elements from the captured web page picture, have been disappeared.
    Where Capturing a whole web page with the "FIRESHOT" Addon the results are Perfect!!
    So, I am going to Uninstall the screengrab addon.

  • With the last update, all the selections (save, preview, upload, etc) that involve full-screen, are grayed out. So there is not possible to save a full screen anymore using this plugin. Can you please fix that, or let me know if I am missing a setting. Thanks for a great plugin.
